Straight, L-Shaped & “U” shaped Heaters (Cont.)
- If using 90 degree elbows in the emitter tube (Part # AC1130) install and secure
using the same methods above. Ensure that all lengths of tube are adequately
supported, using no less than 2 hangers for each 10’ of total tube length. Install
extra hangers to support cut lengths if needed. Tube/reflector material can be cut
to suit in the field, or factory supplied in required lengths.
- U-shaped models: connect the 180 degree bend to the radiant tube and securely
tighten with self tapping screws provided.
- Make sure to secure all tube joints using the 3 screws provided in 120 degree
intervals as indicated in the tube assembly diagram below.
- Heaters incorporating a baffle must have the baffle installed at the vent
end, located at the extreme opposite end of the heater from the burner.
Baffles are typically pre-installed in a 10’ section of tube and are clearly labeled.
- All heaters 40 ft and under require a baffle. The baffle is not to be installed in the
primary tube except for baffles in 20 ft. heaters that have been supplied as one
20 ft. length.
- Reflectors can now be placed in the hangers. To prevent “walking” of the
reflectors, the first and second reflector can be joined together at the overlap with
a sheet metal screw.
Do not attach more than two reflectors together in a
row (i.e. join reflectors 1 & 2 together and reflectors 3 & 4 together etc.).
- With the radiant tube and reflectors now installed, the burner can be fitted to the
flanged end of the primary tube using the nuts provided. The burner does not
require its own hanging support provided the first hanger is no more than 6
inches from the flange
. If the first hanger is more than 6 inches from the
flange, warping of the primary tube may occur and the warranty will be
void.
- Connect the burner to the gas supply using a suitably approved flexible gas
connector as outlined in this manual.
- Install exhaust/intake air venting as outlined in this manual.
- Install thermostat control wiring as outlined in this manual.
TUBE ASSEMBLY
REFLECTOR EXTENSIONS
Reflector extensions (part number P-1930) may be installed on one side or both sides of
the reflector as required to reduce lateral heater output on one or both sides of the unit.
Reflector extensions are 10 ft long x 9”. Drill 3 holes per reflector, and secure
extensions to reflector by means of field provided S hooks
