blocked, the heater will not receive enough

PRECAUTION TO BE TAKEN
WHEN INSTALLING COAXIAL
VENTING
Proper assembly and installation of venting
elbows and tubing must include the use of
self-tapping screws to permanently secure
in place the
internal discharge tube. Self-tapping
screws are used to insure that the
discharge vent tube remains in place and
not allow discharge gases to re-enter the
heater. Failure to secure the internal
discharge tube may result in the heater
backfiring and causing permanent damage
to the heat exchanger. Heaters which have
been damaged for this reason are not
covered in our limited warranty.
The stainless steel (End terminal) wind
guard must fit properly and inter-lock into
slip joint of intake pipe.
It is imperative that the internal discharge
pipe first be secured in place with self-
tapping scews before attaching and
securing the external vent pipe. Also,
ensure that the two grids of the end
terminal come completely out of the outer
pipe. If the intake grid is hidden the heater
will not receive enough air for combustion
and would fail to ignite.
Picture # X: First, insert the vent inner pipe
into the vent elbow and tighten using self-
tapping screws
Picture # Y: Second,
fit the outer pipe and
secure it with proper
screws
