Page 3: Installer Responsibility
1.0) SAFTEY This heater is a self-contained infrared radiant tube heater. Safety information required during installation and operation of this heater is provided in this manual and the labels on the product. The installation, service and maintenance of this heater must be performed by a contractor qualified in the installation and service of gas fired heating equipment. - Page 4 Although these heaters may be used in many applications other than space heating (e.g., process heating), Space- Ray will not recognize the warranty for any use other than space heating. This heater is not an explosion proof heater. Where the possibility of exposure to volatile and low flash point materials exists, it could result in property damage or death.

Tighten the nuts of the Torctite Coupling to secure the Damper Assembly to the Radiant Tube, taking care to support the Damper Assembly in line with the axis of the tube.
- Page 12 9.0) SYSTEM EXHAUST MANIFOLD 1. All exhaust manifold tube is manufactured to a standard diameter. All joint connections, on all sizes of fittings, push fit into the relative tube and should be sealed using high temperature silicone sealant. No locking bands are required. 2.
- Page 13 A. Combustion Air Adjustment (System Cold) It is necessary to adjust the amount of combustion air to each burner in the system by carring out the following procedures: 1. Switch off the electricity supply to each appliance in the system. 2.
- Page 14 A. Combustion Air Adjustment (System Hot) It is IMPORTANT to finally adjust the amount of combustion air to each burner in the system when the system is operating at thermal equilibrium. 1. Operate the system for 20 minutes to attain thermal equilibrium then adjust the amount of combustion air at each burner by carrying out the procedures at 2 to 4 on each appliance in turn.
