Gas lines meet applicable codes

Tubes.; Make sure there are no cracks.; Make sure tubes are connected and suspended securely.; See Page 16, Section 6.; Make sure there is no sagging, bending, or distortion.; Clean or replace as required.; SECTION 6: HEATER INSTALLATION

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

Wear protective gear during installation, operation and service

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

SECTION 10: WIRING DANGER - Electrical Shock Hazard - Disconnect electric before service - Heater must be properly earthed - Failure to follow these instructions can result in death or electrical shock

No exposed wire or damage to the thermostat

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.

Choose the connection for heaters

Heaters must be grounded in accordance with applicable codes: United States: Refer to National Electrical Code® NFPA 70 - latest revision Canada: Refer to Canadian Electrical Code CSA C22.1 Part I - latest revision

Internal wiring replaced with wiring materials having a temperature rating of at least 105 °C and 600 volts

Sign off on the thermostat inspection

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

Make sure nothing is lodged underneath the reflector, in between the tubes, or in the decorative or protective grilles included with select models

Immediately remove objects in violation of the clearances to combustibles
