Manufactured Home Heating Maintenance Tips
It’s very important to make sure your manufactured home furnace operates safely and efficiently during winter weather. You can perform many routine furnace maintenance jobs, while other procedures are best handled by a qualified repair person. Most furnace manufacturers recommend a professional inspection of fuel lines, safety controls, burner and flue pipe every year. Your utility company may provide a free inspection.
You should replace disposable furnace filters regularly. Remove and wash, brush or vacuum permanent filters. Remove the cover of the thermostat and vacuum away dust and dirt. Check the exhaust vent from the furnace. Clear obstructions like leaves or animal nests from the vent pipe. Keep roof exhaust vents clear of excess snow build-up.
Inspect blower motor. Vacuum any accumulated dirt. Inspect V-belt and pulleys for wear. If the belt moves more than an inch when you push it, tighten it. Check air intake. Most manufactured home furnaces draw combustion air from beneath the home, so keep four to six vents in the skirting to allow free air passage.
Check flue assembly for alignment and rigidity. It should run in a straight line from the top of the furnace through the ceiling. Be sure the flue is attached to the furnace collar. Check to make sure there is no loose wiring near the flue. If there is wiring in the flue area, move and secure it well away from the flue pipe.
Carpeting in furnace compartment should be removed and replaced with fireproof material. Some manufactured home furnaces have wire mesh in front of the stack to prevent storage on top of the furnace. If this mesh is missing, replace it.
Clean out debris in furnace area, and don’t allow even small amounts to accumulate. Never use your furnace closet for storage or drying clothes. This is a fire hazard.
