before operating this appliance.
1. Set the thermostat to the lowest setting.
2. Turn off allelectrical power to the appliance.
3. This appliance does not have a pilot. It is equipped with an igni-
tion devicewhich automatically lights the burner. Do not try to
light this burner by hand!
4. Removethe front jacket panel.
5. Turn offthe gas ballvalve.Valve handle should be perpendicu-
lar to the gaspipe.
6. Wait 5 minutes for any gas to clear. Then smell for gas, includ-
ing near the floor. If you smell gas, STOP! Followinstructions
on this page under "What To Do If You SmellGas." If you do
not smell gas, go to next step.
7. Turn gas ball valveto the "on" position. The handle on the valve
should be parallel to the gas pipe.
8. Replacethe front jacket panel.
9. Turn on all electrical power to the appliance.
10. Set thermostat to desired setting.
11. If the appliance will not operate, followthe instructions "To
Turn OffGas To Appliance" (below)and call your servicetech-
nician or gassupplier.

TO TURN OFF GASTO APPLIANCE
1. Set the thermostat to the lowest setting.
2. Turn offall electricpower to the appliance if service is to be
performed.
3. Removethe front jacket panel.
4. Turn gas ball valve off,handle should be perpendicular to the
gas pipe.
5. Replacethe front jacket panel.
6. Safelighting and other performance criteria were met with the
gas manifold and control assemblyprovided on the boiler when
the boiler underwent tests specifiedin ANSI Z21.13-latestrevi-
sion.
The acidic nature of flue gases condensing on the aluminum boiler
sections will cause the formation of aluminum oxide. This oxide
formation is normal, is generallyuniform throughout the boiler
sections, and represents a negligiblemass of aluminum that is con-
sumed by oxidation during the lifeof the boiler. If left unchecked,
this buildup may eventually causeblockageof the flue gas passages in
the boiler sections, reducing efficiency,and ultimately shutting down
the boiler due to lack of combustion air flow,or drainage of conden-
sate.
Regular service and maintenance by a qualified
service agency must be performed at least once
every 12 months to assure safe, trouble free op-
eration and maximum efficiency.
Beginning of each heating season
1. Schedule an annual service call by a qualified service agency
which includes:
•Examining flue passages in the heat exchanger, burner, and
condensate lines, and cleaning (if necessary) by following
the instructions in "Annual Examination and Cleaning of
BoilerComponents" in this section.
•Visually inspecting the venting and air intake system for
proper operation, immediately repairing or replacing any
sign of deterioration or leakage,and insuring proper reas-
sembly and resealingof the system.
•Checking for and removing any obstruction to the flowof
combustion air or venting of flue gases.
•Followingthe instructions in Sections V and VII of
the Control Manual and Operating Instructions (P/N#
240006104),"Putting The Boiler In Operation" and
"Checkout Procedures And Adjustments."
•Visually inspecting the condensate drain line for proper
operation and checking for deteriorated or plugged con-
densate drain line.
•Checking all gasketed joints for leakageand tightening bolts
or replacing gaskets as needed.
•Removing jacket front and top panels, checking for piping
leaks around relief valve and other fittings, and repairing if
found WITHOUT USING stop leak compounds.
•Analyzethe boiler fluid as instructed in Water Treatment
