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 aappliance aarea sshall bbe kkept cclear aand ffree ffrom
combustible m materials, ggasoline, aand oother
flammable vvapors aand lliquids.
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, dirt or any
combustible material. If any operational component
shows signs of rust or corrosion, replace the
component immediately.
6. If any warning or instruction labels, dataplates, etc.
become lost or hard to read, replace them
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.
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.
