a.
Place a Torctite Coupling over the end of the Radiant Tube (refer to Section 10.1 “Tube Coupling Details”).
Assemble the Fan Assembly to the Radiant Tube and position the fan outlet pointing upwards for flueless
applications. Tighten the bolts of the Torctite Coupling to secure the Fan Assembly to the Radiant Tube,
taking care to support the Fan Assembly in line with the axis of the tube.
NOTE: Tighten the Torctite Coupling bolts alternately while continually checking for slackness of the joint.
b.
Assemble the end reflector flush with the end of the main body reflector. Secure by sliding speed clips
(supplied in fastening kit) onto the reflector edges. Evenly space the speed clips on the sides and top of the
reflectors to provide a snug fit.

GAS CONNECTIONS AND REGULATIONS
Tighten flexible gas hose and components securely.
Flexible metal gas hoses must be installed without any twists or
kinks in them. The hose will move during operation of the heater
and it can crack if it is twisted.
Failure to do so may result in death, serious injury or property
damage.
IMPORTANT BEFORE CONNECTING THE GAS TO THE HEATER
a.
Connect to the supply tank or manifold in accordance with state or local building codes. Authorities having
jurisdiction should be consulted before the installation is made.
b.
Check that the gas fuel on the burner rating plate matches the fuel for the application.
c.
Check that the gas supply piping has the capacity for the total gas consumption of the heaters and any other
equipment connected to the line.
d.
Check that the calculated supply pressure with all gas appliances and heaters operating will not drop below
the minimum supply pressure required for these heaters. See Table 11a Below.

e.
All gas supply lines must be located in accordance with the required clearances to combustibles from the
heater as listed on the clearances label of the heater and (Section 4.0) of this manual.
f.
Pipe joint compounds must be resistant to the action of liquefied petroleum gases.
g.
Tube heaters will expand/contract during operation. Use an approved flexible connector for connections
between the rigid piping and the heater. A union should be installed before the control box inlet. An
approved shut off valve should be installed within 1.8m of the union.
h.
The gas pipe, flexible hose and connections must be self supporting. The gas pipe work must not bear any of
the weight of the heater or any other suspended assembly.
