❏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 techni- cian, 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.
