I - FOR YOUR SAFETY
Do not store or use gasoline or other flammable vapors
and liquids in the vicinity of this or any other appliance.
WARNING
If the information in this manual is not followed exactly, a
fire or explosion may result, causing property damage, per-
sonal injury, or loss of life.
A. This appliance does not have a pilot. It is equipped with an igni-
tion device which automatically lights the burner. Do not try to light
the burner by hand.
B. BEFORE OPERATING smell all around the appliance area for
gas. Be sure to smell next to the floor because some gas is heavier
than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
Do not try to light any appliance.
Do not touch any electrical switch; do not use any phone
in your building.
Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions. If you cannot
reach your gas supplier, call the fire department.
C. Use only your hand to push in or turn the gas control knob. Never
use tools. If the knob will not turn by hand, don’t try to repair it. Call
a qualified service technician. Force or attempted repair may result
in a fire or explosion.
D. Do not use this appliance if any part has been under water. Im-
mediately call a qualified service technician to inspect the appliance
and to replace any part of the control system and any gas control
which has been under water.

1. Turn off all electric power to the appliance if service is to be per-
formed.
2. Set the thermostat to the lowest setting.

BLOCKED FLUE/VENT SAFETY SHUTOFF
The Blocked Flue/Vent Safety Shutoff shuts off main burner gas in
the event that the flow of combustion products through the flue ways
is reduced. In the event of blocked flue ways, enough air will not be
available to support combustion, and boiler control will lockout due
to loss of proper air flow.If the boiler can not be restored to normal
operating condition by resetting the control, contact a qualified ser-
vice agency to check the flue ways and vent pipe for blockage.

MAINTENANCE AND CLEANING
Regular service and maintenance by a qualified service agency
must be performed at least once every 12 months (preferably at
the start of each heating season) to assure safe, trouble free op-
eration and maximum efficiency. The boiler owner SHOULD NOT
attempt these procedures.
This annual service should include at a minimum:
Examining the flue passages between boiler sections, burn-
er, and condensate lines, and cleaning if necessary.
Inspecting venting and air intake system and cleaning if nec-
essary.
Placing the boiler in operation and performing the checkout
procedure.
Inspecting the condensate drain pipe and cleaning if neces-
sary.
Checking all gasketed and threaded joints for leakage, and
repairing if necessary.
Particular attention should be given to potential deterioration from
corrosion or other sources. Detailed procedures can be found in
Section XII, “Maintenance and Cleaning,” of the Installation Manual
(P/N# 240006103).
The boiler owner SHOULD perform the following periodic
maintenance procedures.
DAILY DURING HEATING SEASON:
Check for and remove any obstruction to the flow of com-
bustion air or venting of flue gases.
Check that boiler area is free from combustible materials,
gasoline, and other flammable vapors and liquids.

MONTHLY DURING HEATING SEASON:
Remove jacket front and top panels and check for piping
leaks around relief valve and other fittings. If found, con-
tact a qualified service agency. DO NOT USE STOP LEAK
COMPOUNDS.
Test relief valve. Refer to valve manufacturers instructions
packaged with relief valve.
Visually inspect the venting and air intake system for prop-
er operation. If the vent or air intake show any signs of de-
terioration or leakage, contact a qualified service agency
to repair or replace them immediately and to insure proper
reassembly and resealing of the system.
Visually inspect the PVC condensate drain pipe for proper
operation. If the drain pipe shows any signs of blockage,
leakage, or deterioration contact a qualified service agen-
cy to clean, repair, or replace it immediately.
Check air vent(s) for leakage.
Where low water cut offs are used, a periodic inspection
of the low water cut off is necessary, including flushing of
float type devices. Refer to low water cut off manufactur-
er’s specific instructions.
END OF EACH HEATING SEASON (ANNUAL SHUT DOWN
PROCEDURE):
Turn off gas to boiler as described “To Turn Off Gas To Ap-
pliance” in Section V of the Control Manual and Operating
Instructions (P/N# 240006104).
If the heating system is to remain out of service during
freezing weather and does not contain antifreeze, drain
system completely. If the boiler will be exposed to freezing
temperatures, drain condensate lines. Otherwise, do not
drain the system or boiler.
IMPORTANT: Should overheating occur or the gas supply
fail to shut off, do not turn off or disconnect the electrical
supply to the pump. Instead shut off the gas supply at a
location external to the appliance.
