Tankless water heater (EG and EGH only)
If boiler is used to supply domestic hot water, limit
control should be set to supply adequate hot water.
Weil-McLain tankless heaters are rated at 200 °F boiler
water temperature. To get rated output, set low limit at
200 °F. Limit can be adjusted to meet system hot water
requirements. Differential can be set to 15 ° and adjusted
to control level. Lowering the differential will cause a
slight variation in water temperature but will decrease
burner on-off cycling. High limit should be set at least
20 ° above low limit.

User maintenance procedures
Boiler must be serviced & maintained
The boiler should be inspected and started annually, at
the beginning of the heating season, only by a qualified
service technician. In addition, the maintenance and
care of the boiler designated on page 6 and explained
on the following pages must be performed to assure
maximum boiler efficiency and reliability. Failure to
service and maintain the boiler and system could result
in equipment failure, causing possible severe personal
injury, death or substantial property damage.

Boiler area
To prevent potential of severe personal injury, death
or substantial property damage, eliminate all materials
discussed below from the boiler vicinity. If found:
• Remove products immediately from the area. If
they have been there for an extended period, call a
qualified service technician to inspect the boiler and
vent system for possible damage from acid
corrosion.
• If products cannot be removed, immediately call a
qualified service technician to install an outside
combustion air source for the boiler (if not already
installed).
1. Combustible/flammable materials — Do not store
combustible materials, gasoline or any other
flammable vapors or liquids near the boiler.
Remove immediately if found.
2. Air contaminants — See listing of contaminants
on page 3.

Pressure/temperature gauge
or pressure gauge (steam)
1. Water boilers — Make sure the pressure reading
on the boiler pressure/temperature gauge does not
exceed 24 psig. Higher pressure may indicate a
problem with the expansion tank or gauge.
2. Steam boilers — Make sure the pressure reading
on the boiler pressure gauge does not exceed 15
psig. Higher pressure indicates a problem with the
gauge or limit control.
3. Contact a qualified service technician if problem
persists.

❏ Check monthly . . . . . . . . . . . . . . . .
Boiler piping
1. Visually inspect for leaks around piping, circulators,
relief valve and other fittings. Immediately call a
qualified service technician to repair any leaks.
Have leaks fixed at once by a qualified service
technician. Continual fresh makeup water will reduce
boiler life. Minerals can build up in sections, reducing
heat transfer, overheating cast iron, and causing section
failure.
If flame blows out or flickers severely, the vent
system must be checked for obstructions or
other causes of improper venting.
b. Verify the vent damper (CGa and EG boilers)
opens before burners ignite.
3. Notify your qualified service technician at once if
you find any problem.
Boiler relief valve . . . . . . . . .
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to boiler
and system components can occur, resulting in possible
severe personal injury, death or substantial property
damage.
Venting system
Failure to inspect the vent system as noted above and
have them repaired by a qualified service technician
can result in vent system failure, causing severe personal
injury or death.
1. Visually inspect all parts or the flue gas venting
system for any signs of blockage, leakage or joints
or deterioration of the piping.
2. CGa and EG boilers:
a. With boiler firing, hold a candle or match be-
low lower edge of draft hood “skirt.” If flame
does not blow out, but burns undisturbed, the
vent system is working properly.
8 Part Number 550-1 10-592/1099
1. Inspect the boiler relief valve (see Figure 3) and
the relief valve discharge pipe for signs of weeping
or leakage.
2. If the relief valve often weeps:
• water boilers — the expansion tank may not
be working properly.
• steam boilers — limit control may be set too
high or there may be system problems.
• Immediately contact your qualified service
technician to inspect the boiler and system.

The boiler control module will sense blockage of
the air intake or flue and lockout if the blockage is
excessive. It will signal the failure by flashing the
appropriate indicator lights on the control board.
2. If removing the debris does not allow the boiler to
operate correctly afterwards, contact your qualified
service technician to inspect the boiler and vent/
air systems.

Operate boiler relief valve
To avoid water damage or scalding
due to valve operation, a metal
discharge line must be connected to
relief valve outlet and run to a safe
place of disposal. This discharge line
must be installed by a qualified
heating installer or service
technician in accordance with the
instructions in the Boiler Manual.
The discharge line must be
terminated so as to eliminate
possibility of severe burns should
the valve discharge.
1. Before proceeding, verify that the relief valve outlet
has been piped to a safe place of discharge, avoiding
any possibility of scalding from hot water.
2. Read the boiler pressure/temperature gauge to make
sure the system is pressurized.
3. Lift the relief valve top lever slightly, allowing water
to relieve through the valve and discharge piping.
4. If water flows freely, release the lever and allow the
valve to seat. Watch the end of the relief valve
discharge pipe to ensure that the valve does not
weep after the line has had time to drain. If the
valve weeps, lift the seat again to attempt to clean
the valve seat. If the valve continues to weep
afterwards, contact your qualified service technician
to inspect the valve and system.
5. If water does not flow from the valve when you lift
the lever completely, the valve or discharge line may
be blocked. Immediately shutdown the boiler,
following the instructions on the inside jacket top
Lighting Instructions. Call your qualified service
technician to inspect the boiler and system.

❏ End-of-season shutdown . . . . . . . .
Follow boiler shutdown procedure
1. Follow “TO TURN OFF GAS TO APPLIANCE” on
the Lighting/Operating instructions on the inside
of the jacket panel. You will also find these
instructions on pages 13 through 22 of this manual.
Use the Lighting/Operating instruction for the gas
valve model installed on the boiler.
2. Do not drain system unless exposure to freezing
temperatures will occur.
3. Do not drain the system if it is filled with an
antifreeze solution.
4. Do not shut down boilers used for domestic water
heating. They must operate year-round.
Propane gas odorant
Propane boilers only — Your propane supplier mixes an odorant with the propane to make its presence detect-
able. In some instances, the odorant can fade and the gas may no longer have an odor.
• Propane gas can accumulate at floor level. Smell near the floor for the gas odorant or any unusual odor. If you
suspect a leak, do not attempt to light the pilot.
• Use caution when attempting to light the propane pilot. This should be done by a qualified service technician, particularly if pilot outages are common.
• Periodically check the odorant level of your gas.
• Inspect boiler and system at least yearly to make sure all gas piping is leak-tight.
• Consult your propane supplier regarding installation of a gas leak detector. There are some products on the
market intended for this purpose. Your supplier may be able to suggest an appropriate device.
