Burner Adjustment; Furnace Checkout Procedure - Thermo Pride CLQS1-050T36N Installation And Operation Manual

All installations and services must be performed by qualified service personnel.
D. BURNER ADJUSTMENT
This unit is designed to require no burner adjustment. Flames should be visually examined at the start of
the heating season and monthly during the heating season. The flames should be checked by looking
through the sight glass in the combustion door and observing the flames inside the burner box. Burner
flames should be clear, blue and almost transparent in color. (See Figure 16). Burner flames should not
impinge or fire against the side of the tube opening. NOTE: It is not unusual to have orange tipped
flames visible in the tube for Propane gas.
: These furnace models are an in-shot burner design, which does not require an air
shutter adjustment (air shutters are not used) for proper flame characteristics. Combustion door
should always be in place when operating furnace.

gas tight as indicated in the manual.
