INSTALLATION (2 OF 2)
STEP
6
Lift the burner into place and suspend it by inserting the S-
hook of the safety chain into the center hole of the safety
chain bracket, and then crimp the hook closed. Insert the
burner tube into the tube clamp at the burner end of the
combustion chamber. Make sure that the burner tube is
inserted against the center stop inside of the tube clamp.
Then, tighten the clamp as described in step 7.
NOTE: The safety chain for the burner has 6” (15 cm) of
slack. It is
NOT
taut.
STEP
7
Tighten all tube clamp nuts on all tube clamps. Tighten nuts
a half turn at a time, in a 2, 3, 4, 1 sequence, where 1 is
always closest to the burner. Tighten nuts with a torque
wrench until the flanges of the clamp touch and 65 ft.-lbs.
(88 Nm) is achieved at each nut to assure proper seating of
the clamps’ inner sleeve. Do not pinch clamp hanger
between flanges. S-hook of clamp must be closed after
inserting chain.
STEP
8
Lift reflectors into place and install on reflector brackets.
Make sure not to soil the polished underside of the
reflectors. Gloves are suggested. Insert the double turned
edge of the reflector under the reflector bracket tab. Be
certain the spring steel clamp is in place to hold the reflector
securely as shown. If the reflectors are to be at an angle,
loosen the two (2) nuts holding the two (2) reflector brackets
in place and rotate reflector and brackets into desired
position. Reflectors must not be angle mounted more than
30° from horizontal for 65 to 125 MBTUH (19 – 37 kW) or
45° from horizontal for 40 to 60 or 130 to 200 MBTUH (12 –
18 or 38 – 59 kW).
If located near a large doorway or in
an area affected by wind see the WINDY CONDITION
NOTES section.
STEP
9
For U-tube construction, see the BASIC SYSTEM
CONFIGURATIONS section for placement of the 180°
bend. Otherwise, installation procedure is the same as
above. See also the U-TUBE INSTALLATION section.
CAUTION
IMPORTANT
•
Make sure all chains are plumb and vertical. A chain
that is not plumb and vertical may cause damage to the
radiant tube it suspends.
•
Connect the gas supply as instructed in the GAS
SUPPLY AND GAS PRESSURE section.
•
Connect the electrical supply as instructed in the
ELECTRICAL SUPPLY AND THERMOSTATIC
CONTROL section.
