It is important for these vents to remain clear. Do not allow moisture, which could freeze, to build up in the vent.
If you see moisture building up in the regulator vent, contact your gas supplier.

GAS METER
Most natural gas systems and all LP gas systems have
a service regulator located near the point where the gas

piping enters the building.
The propane tank will normally have an additional fi rst
stage regulator located at the tank outlet valve. All of
these regulators (located outdoors) will have a vent.

ROUTINE MAINTENANCE
QUARTERLY:
•
We recommend a monthly filter inspection at first, then every three months afterwards.
YEARLY:
•
Priming Trap needs to be inspected at every starting season. Add more water if necessary.
•
Check that barbed fitting caps are tight and condensate lines remain clean and secured by hose clamps.
WE RECOMMEND THAT YOUR UNIT AND EXHAUST/COMBUSTION AIR VENTS BE CHECKED
It is good practice to give a quick inspection of your unit each time you inspect or clean the air fi lter.
Things to check:
•
Check the unit for obvious signs of deterioration.
•
Check the venting and combustion air piping to ensure that it is still fastened to the unit. It should not sag,
and should have a 1/4" (6mm) per foot (305mm) slope upwards, to the outside wall or termination.
•
There should be no water marks on the fl oor under the venting. Water marks may indicate a leaking pipe joint.
•
All ductwork should be secured to the unit, and all ductwork should be solidly supported throughout.
•
Water should fl ow easily through the condensate drain lines. You may be able to observe this while the
unit is operating if your condensate drain line from the drain trap assembly terminates at a fl oor drain. If the
drain lines are opaque, your service technician will check them during the annual servicing.
•
The gas burner should be observed from time to time during the heating season to ensure that the fl ames
are clean and blue. A bit of orange color in the fl ame is not likely to be a problem and is probably dust
particles burning. If you observe lazy yellow fl ames, call your heating or service contractor immediately.
The yellow fl ames inevitably lead to soot-ups.
•
The combustion air and exhaust terminals should be inspected occasionally to ensure that they are free of
obstructions and debris.
