Airtronic Heaters-How To Remove Carbon buildup

Arctic Traveler Canada is a master distributor and technical service expert for ESPAR Airtronics and Hydronics Heaters.

How To Remove Carbon buildup on Airtronic D2 and D4 Burners


To help identify when a burner has excessive carbon build up, Click here and follow the recommendations.

In the event that the burner / flame tube and combustion chamber of the Airtronic D2 or D4 becomes restricted and the heater fails due to carbon/soot build up it may be possible to clean the burner without disassembling the heater by running the heater in high using Kerosene instead of Diesel.

Since the replacement of a burner with carbon build up is not covered by warranty unless the carbon was caused by a defective heater or component this bulletin will assist in reducing the cost and time of cleaning a burner that has caused the heater to fail due to excessive carbon build up.

The excessive build‐up of carbon in the heater is not a result of normal operation of the heater. The build‐up of excessive carbon or soot in the burner / combustion chamber and flame tube as well as the inside of the heat exchanger is in most a symptom of an underlying problem which is the root cause. Therefore, it is very important to identify and correct the root cause so that the burner does not become restricted again. Please refer to the troubleshooting guide and fault code list to identify the problem. Also refer to the installation instructions to make sure the heater and accessories are installed according to the installation guidelines using the correct parts. 

In some cases the carbon build up in the burner may be too severe and the burner would need to be replaced. Unless the root cause of the carbon build up is corrected the replacement or cleaning of the burner will not result in a permanent solution but only a temporary fix.

How To Determine and Remove Excessive Carbon Build up in Espar Heaters.


One way to identify if the burner in your Espar Heaters may have excessive carbon build up is to look into the exhaust outlet of the heater with the flexible exhaust pipe removed.
This may be difficult while the heater is installed due to its location but with the assistance of a mirror and a flashlight it can be accomplished.
Intake and Exhaust outlets of the Espar heaters
Another way to find out if the burner has excessive carbon build up is to inspect the glow pin screen chamber and look into the burner as much as possible.
If the bottom of the glow pin screen chamber is blocked or partially restricted it may be an indication that the burner could have carbon build up.

When Espar heaters have failed to start due to excessive carbon build‐up in the burner, the heater may produce a Fault Code 52 which is Safety Time Exceeded.
This indicates that the heater was not able to start within its allowed start up time. This may also be accompanied by excessive white smoke.

CAUTION:
During the cleaning process of the heater it is likely that hot pieces of carbon will come out of the exhaust pipe of the heater. Make sure that there is nothing on or around the exhaust that could be ignited by these particles. For example, oily rags, fuel spills, the kerosene container or any other flammable material or substance.
Do not look into exhaust pipe or expose unprotected part of your body to the exhaust outlet.

It is the responsibility of the technician who is performing this method of carbon removal to ensure all safety regulations for working with fuel, are met during the procedure.

Alternate method of cleaning Espar Heaters

  • Remove the glow pin using the glow pin removal tool, Espar part number 25 2069 01 03 03 and replace the glow pin screen, Espar part number 25 2069 01 03 00. Make sure the ventilation hole on the side of glow pin chamber is completely clear and not restricted or plugged. Clean the glow pin screen chamber with a brush before inserting the new glow pin screen.
  • Reassemble the heater back to operating condition.
  • Make sure all sources of ignition are kept a safe distance away from the fuel lines and the container of kerosene.
  • Remove fuel line from inlet side of fuel pump.
  • Replace this fuel line with another section of fuel line which is an appropriate length and secure one end to inlet side of fuel pump and other end into a flammable safe container of Kerosene. Espar plastic fuel tank or another approved container may be used.
  • Make sure that the fuel lines and fuel container are not near any sources of heat. Make sure the fuel lines do not touch the exhaust systems of the vehicle, or the Heater.
  • Ensure end of fuel line is securely fastened to fuel pump as to not allow any air to enter fuel system during operation.
  • Ensure Kerosene container is not placed near the air intake or exhaust of heater; this will prevent any fumes to enter combustion chamber and also prevent any sparks or hot particles from igniting the Kerosene.
  • Turn on the heater. This may take several attempts to prime fuel lines.
  • Adjust Thermostat or Mini Controller to the highest temperature set point. If necessary, open vehicle doors allowing cool air in. This will ensure that the heater runs in boost.
  • Some heaters with excessive carbon build up may not start using kerosene and will give a Fault Code 52: Safety Time Exceeded. These heaters may require that they be disassembled and cleaned manually.
  • Allow heater to run in boost for approximately 25‐30 minutes.
  • Turn heater off
  • After the heater has completed its cool down cycle, the fuel line can be removed from fuel pump and container. Container can be removed from the area and safely stored away.
  • Reinstall original fuel line back to inlet side of fuel pump.
  • The heater can now be operated as usual.

A/C Preventative Maintenance

When it comes to air conditioning a good preventative maintenance program will increase operating time and save money by identifying concerns before they become problems. Once the hot weather arrives, implementing planned maintenance allows you to schedule repairs versus reacting to sudden unexpected issues. A/C filters, coils, and fins require regular maintenance to ensure optimum performance and neglecting necessary maintenance ensures a steady decline in performance and increases energy use. 

Filters

Clogged, dirty filters restrict airflow and reduce a system’s efficiency. When airflow is restricted, the air that by bypasses the filter will carry dirt directly into the evaporator coil and reduce the coils heat absorbing abilities. To ensure efficiency routinely clean or replace filters.

Coils

The condenser and evaporator coils collect dirt over time but a clean filter helps to keep the evaporator performing. Debris reduces air flow, insulates the coil and reduces it’s ability to absorb heat. Being exposed to the elements, you can easily see dirt collecting on the fins. Cleaning the coil fins and removing any debris around the coil will ensure optimal performance.

Coil Fins

The aluminum fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a “fin comb” that will comb these fins back into nearly original condition.

Remember to always use caution when performing preventative system maintenance, as ambient conditions (heat load) will increase refrigerant hose temperatures and don’t forget having the right quality parts on hand makes all the difference.

A/C Systems – How a simple inspection can save

RedDot

Tech Tips From RedDot – 
Heavy-duty A/C components rarely fail. In fact, the system fails the components because of contaminated refrigerant oil and general lack of preventive maintenance.

One of the best ways to improve uptime and reduce maintenance costs for the customer is to promote a basic visual check of major A/C components, hose connections, and fittings at regular intervals, like with every engine-oil change. This inspection routine has another benefit: it can generate business for your parts and service department. 

Many A/C components are consumable items. It’s more cost-effective to replace them than to repair them. So preventive maintenance is an opportunity to sell a range of OEM-quality all-makes replacement parts for the air conditioner. Here are some examples:

1. RECEIVER DRIERS

The receiver-drier’s moisture indicator provides a quick visual cue about the refrigerant’s condition: a blue dot means the refrigerant is dry; pink, white, or grey indicates acid or moisture in the system. Checking the sight glass during an oil change or any scheduled maintenance procedure means the truck can receive necessary service while it’s there in the shop, before moisture and acid damage critical A/C components and lead to a failure on the road.

2. CONDENSERS

Dust, bugs, feathers, and other debris collect on the face of fins and tubes and act as a thermal barrier, making it hard for the condenser to shed heat. Condensers also fail because of vibration, which can cause hose connections to come loose and fatigue the condenser tubing adjacent to the fittings. Every 12 months, the condenser should be cleaned (taking special care not to bend or damage the fins) and the hose connections securely clamped.

3. COMPRESSOR/CLUTCH ASSEMBLY

The compressor provides the mechanical energy to circulate refrigerant and manipulate the pressure inside the system. It’s the heart of the A/C system, and the No. 1 HVAC maintenance expense item. Excessive noise and poor cooling performance are the two most obvious symptoms that a compressor is failing. Replacing the compressor involves pulling down the system, which adds refrigerant recovery and recharge to the repair cost.

Next time you see, “A/C won’t blow cold air” on a work order, note that the repair and downtime probably could have been avoided with a simple visual inspection of the truck’s air conditioning system. Any time you change the truck’s oil, check the A/C.
