MAINTENANCE (cont.)
out. Do not attempt to pass anything through the pilot
orifice. Next, check the main burner for dirt, lint or carbon
deposits. Again, if any is noted, clean with a soft brush.
7. Inspect the interior of the combustion chamber for dirt, lint
or carbon deposits. If any are found, loosen them with a
long handled brush and remove the residue from the heater
with a vacuum cleaner.
8. In preparation for replacing the main burner/pilot, check
the condition of the gasket on the mounting plate. If the
gasket appears damaged or worn, replace ONLY with a
gasket available from Empire Comfort Systems Inc.,
whose address is at the bottom of this page. Install the
assembly in the heater and re-secure the assembly to the
heater chassis with the four screws removed in step 6
above. Note: verify that the left side of the main burner
is mounted on its support bracket. The burner should
be level.
9. R econnect the main burner and pilot gas lines which were
disconnected in step 6 above. Reinstall the thermocouple
in the pilot bracket, inserting it fully into chamber before
tightening.
10. Replace the heater on the wall support bracket, taking
extreme care to ensure that the small diameter vent pipe is
firmly engaged with the vent outlet at the rear of the
heater. The large diameter vent pipe will slide over the
appropriate opening. Resecure the unit to the bracket with
the two screws removed earlier.
11. Reconnect the gas supply piping and REPEAT THE LEAK
TEST PROCEDURE. In addition, it will be necessary for
you to check the gas connections inside the unit for leaks.
After testing the gas connections to the unit, place the pilot
burner into operation by following the instructions found
in this manual or on the hanging tag behind the unit. Che ck
all joints to the pilot gas line with a soapy water
solution. Bubbles on any of the joints indicated a leak is
present and must be repaired. Turn OFF the gas to the unit
when performing any repairs to the gas piping system.
After the pilot lines are checked, turn the main burner ON
and again check all joints in the piping system for leaks
with soapy water. Repair any joints which indicate a leak
is present.
12. While the main burner is ON, check the pilot and burner
flames to see that they are burning a clean blue color. See
Figures 11 and 12 for an approximation of the correct
flame pattern. If your unit is not burning cleanly, or if you
are not sure, turn the unit OFF and contact the gas supplier
or call Empire Comfort Systems Inc..
Before completing your periodic maintenance checkout,
ensure that the appliance area is clear and free from
combustible materials, gasoline, and other flammable vapors
or liquids. Also check to see that the flow of combustion and
ventilation air around the vent cap on the outside of the
structure is not obstructed.
Note: verify proper operation after servicing.
