Gas Fired Tube Heater Maintenance

Gas Fired Tube Heater Maintenance

Power to the heater should be turned off during the summer months, to protect the heating controls from exposure to electrical surges. This precautionary step can extend the life of the heating controls.

It is good practice to inspect the tube heater at the beginning of each heating season.

Maintenance shall be performed by a trained gas professional, Do not attempt this without the proper training. Maintenance is best performed at the beginning of the heating season, typically in late summer or early fall.

The blower wheel in the burner can have dust build up that can have negative effects on performance of the heater.  A good burst of compressed air can be used to clean the wheel. The clean wheel will ensure that the heater is getting the adequate air flow for proper combustion.  Keeping the blower wheel dust free can extend the life of your heat exchanger.

Upon inspection, it is also common to find spider nests, which are usually found behind the gas orifice.  This can cause a gas restriction or blockage, which can prevent the heater from lighting or can significantly decrease heat production.   The heater may have manifold pressure present, even with no gas flow. It is a good idea to access the gas orifice and remove it. Typically you will see evidence of a spider nest right inside or behind the orifice. Disassemble, as required, to clean this out.

It is also a good time to inspect the reflector system to be sure that nothing has been altered from its proper position during the summer months.

Completing this routine inspection will ensure that your infrared heating system is ready to warm your space when the outside temperatures begin to drop.
