14− Reinstall ignitor and sensor bracket assemblies on
burners.
NOTE − Ignitor must be installed on the opposite side of
the burner from the metal button protrusions. Screws
which attached the ignitor bracket must be installed
from the same side as the ignitor and through the brack
et to engage in the smaller holes located in the burner.
The correct burner orientation is with metal button pro
trusions always pointing up.
15− Replace burner ignitor assembly back into burner box
so that grommet groove fits back into sheet metal
notch and makes a good seal. The burners sit on top of
the burner box flanges. Make certain that the screws
from underneath the box pass through the larger holes
in the flange and engage in the smaller holes in the
burner. Reinstall the two screws.
16− Reinstall the gas manifold/gas valve assembly by first
inserting the right hand side of the gas manifold into the
burner box. Swing left side of manifold into box while en
gaging support bracket to vestibule panel screws.
Check that foam gaskets are providing a seal around
each end of the gas manifold. All gas orifices should be
engaged. If at this point the burners were mounted in the
wrong holes, this needs to be corrected. The saddle
brackets on the gas manifold should be flush with the
front surfaces on the burner box sides.
17− Inspect the dual layered metal pieces at the front lip of
the cover. These pieces must sandwich around the
metal. Reinstall burner box cover.
18− Reinstall the screws to secure the burner box cover.
Make sure screws are tight to ensure a leak tight burn
er box. Tighten the two screws underneath the box.
Again, inspect the grommet to ensure a tight seal.
19− Tighten the two screws holding the manifold bracket to
the vestibule panel.
20− Reinstall the electrical connections to the gas valve.
Brown wire to H1, yellow wire to C2 and orange wire to
M.
21− Re−install the sensor wire to the spade connector on
the SureLight control. Reinstall the 2pin ignitor plug
at the burner box.
22− Reconnect gas line to gas valve.
23− Replace lower access panel.
24− Following lighting instructions and gas line connection
test procedures from installation manual.
25− Replace upper access panel.
C−Supply Air Blower
1 − Check and clean blower housing and blower wheel.
2 − Motors are prelubricated for extended life; no further
lubrication is required.
D−Electrical
1 − Check all wiring for loose connections.
2 − Check circuit breaker located in unit control box.
3 − Check for correct voltage at unit (unit operating).
4 − Check ampdraw on blower motor.
Motor Nameplate_________Actual_________
E−Intake and Exhaust Lines
Check intake and exhaust lines and all connections for
tightness and make sure there is no blockage. Also check
condensate line for free flow during operation.
F−Insulation
Outdoor piping insulation should be inspected yearly for deteri
oration. If necessary, replace with same materials.
G−Winterizing and Condensate Trap Care
1 − Turn off power to unit.
2 − Have a shallow pan ready to empty condensate water.
Avoid spilling water into the control box.
3 − Remove clamp from flue assembly and remove boot or
cap. Empty water from cap. Visually inspect bottom of
flue assembly. Replace boot and clamp.
4 − Remove boot from condensate trap and empty water.
Inspect trap then replace boot.
