1. Join the tube flanges of the 15 ft. body section to the appropriate 5 ft or 10 ft. body sections with the tube flange gaskets
in between. Secure the flanges with the ¼-20 screws and locknuts provided in the body package. NOTE: The #42882030
body section has one tube with a 6-hole flange. This is for connection of the control box on the LTU225 or LTU250
heaters only. It is a special, high-temperature, Alumi-Therm tube designed for use with these higher input heaters only.
Failure to attach the control box to the 6-hole flange will void the manufacturer's warranty.
2. Pull the reflector on the 15 ft. body section over the reflector on the 5 ft or 10 ft body section to maintain approximately a
1-inch overlap. Secure the reflectors by sliding the speed clips on the reflector edges as shown in the following illustration.
One speed clip is required for each side of the reflector. Once the reflectors are secured with the speed clips as shown,
tighten the reflector clamps, making sure that the reflector can slide under the clamps during heater operation.
3. Assemble the control box, draft inducer, & other components as previously described in the heater assembly instructions.
