Periodic Burner Inspection

Following initial start up of the burner, you should inspect the operation of the burner periodically--ideally on a

monthly basis. Doing so ensures that the system is functioning efficiently and safely.

Follow these guidelines for inspecting the operation of the burner:

• Visually inspect the flame length through the observation

port; the flame should extend no more than one-half of

the way down the combustion chamber.

-If the flame is diminishing or displays wide

variations, clean the canister filter and check

valve/screen (procedures provided in this

section).

-If the flame is firing too strongly (i.e. flame

touches back and/or side walls of the

combustion chamber), check the air pressure setting (see following guideline).

• Check the air pressure by observing the air gauge; proper air pressure settings are provided in

Section 6. DO NOT overfire the burner; doing so on a continual basis will damage the furnace.

• Check the combustion air band setting for the proper opening and clean away any dust/debris as

necessary. Note that the air band should NEVER be set fully open or closed.

• Check the draft over fire reading as specified in Section 8.
