Service Instructions
1. Close the fuel supply valve to the heater before
servicing unless it is necessary to have it open for
your service procedure.
2. For reassembly, reverse the respective ser vice
procedure. Ensure gas connections are tightened
securely.
3. After servicing, start the heater to ensure proper
operation and check for gas leaks.
4. Clean the heater’s orifice with compressed air or a
soft, dry rag. Do not use files, drills, broaches, etc. to
clean the orifice hole. Doing so will enlarge the hole,
causing combustion or ignition problems. Replace
the orifice if it cannot be cleaned properly.

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. The heater’s surrounding area shall be kept clear and
free from combustible materials, gasoline, and other
flammable vapors and liquids.
3. 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.
4. 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.
5. 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. If any operational component
s h ow s s i g n s o f r u s t o r c o r ro s i o n , r e p l a c e t h e

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 that are suspect.
IMPORTANT
If it becomes apparent that a dark spot has formed part way
up on the inner combustion cone or a build up of debris is
occurring in the bottom of the inner cone, it will be
necessary to clean out the combustion cone assembly.
