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.

matically lights the burner. DO NOT TRY TO LIGHT THE BURNER

BY HAND.

5. Remove the front jacket panel.

6. Turn the gas control valve clockwise to “OFF”. The handle of

the valve should be perpendicular to the pipe in the “OFF” position.

5. Replace the front jacket panel.

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.
