Fig. 12 VENTING CHECK
The installation is satisfactory if smoke is
drawn into the draft diverter.
If the vent is blocked or has strong reverse
flow, the thermally actuated switch mounted
in the draft diverter opening will automatically
shut off the gas supply within about five
minutes.
If the smoke is not drawn in, leave for about
ten minutes and then try again.
If the smoke is still not drawn into the draft
diverter, turn the heater off and check cause of
lack of draft. if necessary get expert advice.
11. AERATION ADJUSTMENT (See Fig. 13)
Natural gas appliances have adjustable
shutters to control primary aeration on
both rear and front burner tubes.
Propane appliances have an adjustable
shutter on the front burner tube only.
The air holes are at the right side of the
tubes. The appliances are supplied set at
maximum aeration. For the majority of
installations no adjustment will be necessary.
However, in a few instances, performance
may be improved by reducing the aeration
by sliding the shutters to the left or right.
Evaluate the aeration only after the heater
has warmed up (approximately 15 minutes).
Decreasing aeration will cause the flames to
appear more yellow or orange revealing less
glow In the logs. Too little aeration may
result in black carbon forming and dropping
into the firebox.
