B) DIRECT VENT MODELS 

Check air shutter on the 

burner tube (venturi). 

Adjust air shutter. 

Close until flame sits onto 

the burner ports. 

Seal exhaust tube with high 

temperature silicone. 

Also make sure that 

combustion air pipe is 

sealed. 

Make sure there are no leaks 

in the venting system. 

Make sure the unit is not 

recirculating flue products. 

Check flue for blockage or 

high wind situations. 

Use a manometer to check 

gas outlet (manifold) 

pressure. 

SEE PAGE 5 FIGURE 7. 

Make sure the gas pressure 

is correct for fuel being used.

Make sure the orifice size is 

the same as the rating plate.

Correct if necessary. 

Add a vent restrictor ring. 

SEE OWNERS MANUAL. 

Only if necessary.
