Operate the 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 qualied 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 ows 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.
a. If the valve weeps, lift the seat again to attempt
to clean the valve seat.
b. If the valve continues to weep afterwards,
contact your qualied service technician to
inspect the valve and system.
5. If water does not ow from the valve when you lift
the lever completely, the valve or discharge line
may be blocked.
a. Immediately shutdown the boiler, following the
instructions on the inside jacket top Operating
Instructions.
b. Call your qualied service technician to inspect
the boiler and system.

Boiler Shutdown Procedure
1. Follow “TO TURN OFF GAS TO APPLIANCE”
on the Operating Instructions on the inside of the
jacket panel. You will also nd these instructions
on pages 6-11 of this manual.
a. Use the Operating Instructions 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 lled 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 detectable. In some instances, the
odorant can fade and the gas may no longer have
an odor.
• Propane gas can accumulate at oor level. Smell
near the oor 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 qualied 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.
