ADJUSTING BYPASS HANDLE
The bypass handle has to be adjusted over time to
achieve a good seal on the bypass door gasket. The
“latch” where the bypass handle is positioned into
when closing the bypass door can be adjusted.
Undo the two bolts so the latch can be moved to the
required position.
Check the fit of the door gasket. Insert a narrow strip
of paper into the bypass door opening and close
and latch the bypass door. Obvious resistance
should be felt when pulling the paper out. Repeat
this check several times around the perimeter of the
bypass door.
When further adjustment is not possible anymore
with the latch, unbolt the handle, rotate the required
angle and tighten bolts again.

BYPASS DOOR GASKET REPLACEMENT
1.
If the bypass door gasket is to be replaced, be sure you have some 7/8” fiber glass gasket material, ready to re-
install. This gasket is different then the door gasket. Both are 7/8” but the bypass door gasket is a denser material.
See your Blaze King dealer.
2.
Be sure the fire is out and the furnace has cooled down. The door does not have to be removed from the furnace.
Open the bypass as far as possible for easy access.
3.
With a pair of pliers, pull the old door gasket out of the channel and dispose of it.
4.
Thoroughly clean out the channel so the new silicone adhesive will adhere and the gasket will fit smoothly.
5.
Run a small bead of a high temperature silicone adhesive (such as G.E. Silicone Sealer, or the equivalent) along the
center of the channel. DO NOT USE HOUSEHOLD SILICONE CAULKING. High temperature silicone may be
obtained from most auto parts stores.
6.
Start the new gasket in a corner. Do not stretch or cut the gasket. Distribute the gasket evenly around the channel.
7.
Close the bypass door and allow the adhesive to dry.
