1. Have your gas supplier check all gas piping annually
for leaks or restrictions in gas lines. Also, at this time
have your gas supplier clean out the sediment trap
on the zone control panel of any debris that may have
accumulated.
2. Regulators can wear out and function improperly.
Have your gas supplier check the date codes on all
regulators installed and check delivery pressures to
the appliance to make sure that the regulator is
suitable for continued use.
3. Regulators must be periodically inspected to make
sure the regulator vents are not blocked. Debris,
insects, insect nests, snow, or ice on a regulator can
block vents and cause excess pressure at the
appliance.
4. For safety as well as for optimum performance at the
heater, it is necessary to keep the inside and the
outside of the heater free of dust, dir t or any
combustible material.
5. Immediately replace components which show signs
of rust or corrosion.
6. If any warning or instruction labels, dataplates, etc.
b e c o m e l o s t o r h a rd to r e a d , r e p l a c e t h e m
immediately. Do not operate the heater until you
have all instructions and can read and understand
them.
7. Check overall condition of heater for cracked or
damaged components, loose screws or bolts, etc.
Replace any suspect components.
8. Check all hose and tubing assemblies for cracks,
abrasions or ruptures. Replace any hoses that are
suspect.
9. The heater should be cleaned every 6 months, the
filter every 3 months. Cleaning the the heater and
filter is essential for proper heater operation.
Cleaning frequency is dictated by severity of dust in
room
Problems associated with lack of cleaning are:
■
Black soot on inside of canopy.
■
Gas backflashing in venturi tube or injector body.
■
Burner flame appearing beyond outer cone.

CLEANING THE HEATER
Use water at standard faucet pressure. DO NOT USE HIGH
PRESSURE WASHERS!
a. Remove the filter.
b. Spray water up into the cones to wash out the build
up of dust in the cones and the venturi tube. Work
your way around the entire cone assembly. Reverse
the process and run water through the air intake and
out through combustion cones. See Fig. 15.
c. Repeat until water runs clean.
d. Install filter.
e. Light the heater to allow drying.
CLEANING THE FILTER
- Remove filter and shake off excess dust.
- Use water at standard faucet pressure
pressure.
--Do not use high pressure water, or a
washing machine. Filter material damage
may occur.
- Squeeze out excess water from the filter before
installation.
- Let filter dry before lighting heater.
