Do not store or use flammable objects, liquids, or vapors near the heater

Immediately remove these items if they are present

Maintain the clearances to combustibles

Do not hang anything from, or place anything on, the heater

Reflector.; Support reflector with reflector hanger and support strap.; Reflector must not touch tube.; Make sure there is no dirt, sagging, cracking, or distortion.; Do not operate if there is sagging, cracking, or distortion.; Make sure reflectors are correctly overlapped.; See Page 25, Section 6.5.1.; Clean outside surface with a damp cloth.; Step 6.5.1 Reflector, U-Clip and Reflector Support Installation

The pictorial drawings of the heater construction in Section 6 are schematic only and provide a general guideline of where hangers, reflector supports and U-clips are to be installed

To ensure proper expansion and contraction movement of the reflectors, a combination of U-clips and reflector supports are used

The positioning of reflector supports and U-clips depend on the individual installation

Use either pop rivets or sheet metal screws instead of u-clips when installing end caps and joint pieces in areas where impact and high wind may be a factor

The following rules must be observed

Slide first reflector after burner a minimum 2” (4 cm) through first hanger and ensure reflector end cap is securely fastened via U-clips, pop rivets, or sheet metal screws

Position reflector support with tight screws in middle of first reflector

The overlap at the first and second reflector is a slip overlap

Thermostat.; There should be no exposed wire or damage to the thermostat.; See Page 47, Section 10.; SECTION 10: WIRING DANGER

Disconnect electric before service

Heater must be properly earthed

Failure to follow these instructions can result in death or electrical shock

Heaters can be controlled using several methods

Normally thermostats are used to control the heaters but they can also be controlled by an energy management system

Section 10.1 illustrates the connection for heaters controlled by a line voltage thermostat

For heaters on a low voltage thermostat, See Page 48, Section 10.2

Check if tubes are connected and suspended securely

Check for sagging, bending, or distortion in the tubes

Check if tubes are clean or need replacement

WARNING: Severe Injury Hazard. Secure burner to burner tube with nuts and lockwashers. Hang heater with materials with a minimum working load of 75 lbs (33 kg). Failure to follow these instructions can result in death, injury or property damage.

WARNING: Cut/Pinch Hazard. Wear protective gear during installation, operation and service. Edges are sharp. Failure to follow these instructions can result in injury.

Check if the heater is installed in accordance with the instructions

Check if the gas or electrical supply lines are not used to support the heater
