AHE Series 4 Direct Vent Wall-Mounted Boilers — User’s Information Manual
User maintenance procedures continued
Operate 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 AHE Series 4 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 Operating
Instructions on the inside of the jacket top panel or on pages
10 and 11 of this manual. Call your qualified service
technician to inspect the boiler and system
❑ Every 6 months ........... ❑ End of season ..............
Shut down procedure
1. Follow “TO TURN OFF GAS TO THE APPLIANCE”
instructions found in the Operating Instructions located on
the inside of the jacket top panel. You will also find these
instructions on pages 9 and 10 of this manual. 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 filled with an antifreeze
solution.
4. Do not shut down boilers used for domestic water heating.
They must operate year-round.
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 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.
