Page 5: Minimum Clearances To Combustibles
This heater is for Indoor Installation only and can be used in Unvented mode. The term Unvented actually means Indirect Vented. While the products of combustion are expelled into the building, national codes require 4 CFM/1000 BTU of heater input ventilation in the building to dilute these products of combustion. This ventilation may be provided by gravity or mechanical means. - Page 6 A critical safety factor to consider before installation is the clearances to combustible materials. Clearance to combustibles is defined as the minimum distance you must have between the infrared surface, or reflector, and the combustible item. Considerations must also be made for moving objects around the infrared heater. The following is a partial list of items to maintain clearances from: Combustible Items Include: Moving Objects Include:...

Page 8: Rsca Dimensions
RSCA DIMENSIONS HANGING The heater can be mounted with the reflector horizontal or angled up to 45º from horizontal. When the heater is to be angle mounted, make sure the gas manifold assembly is on the lower side of the heater. Coil chains (No. 2 or larger) or rigid supports may be used to mount the heater, which must be suspended from a permanent structure with adequate load capacity. -
Page 9: Optional Parabolic Reflector Extension Assembly
OPTIONAL PARABOLIC REFLECTOR EXTENSION ASSEMBLY The heater is completely factory assembled and requires no field assembly. If the optional parabolic reflector extension is utilized, locate and identify the end panels and side panels as shown in the following diagram. Attach the side panels as shown. Attach the end panels so that the end flanges of the end panels overlap the side panels. - Page 10 1. Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI Z223.1), and local building codes. Authorities having jurisdiction should be consulted before the installation is made. 2. All gas supply lines must be located in accordance with the required clearances to combustibles below the heater as listed on the nameplate of the heater.

All measurements MUST BE made when the heater and all other gas burning equipment that is connectied to the gas supply system are operating at maximum capacity.
- Page 13 Turn off all electrical power to the system to connect manometer hoses. Turn the pressure test screw in the center of the boss not more than one turn counterclockwise. Attach a 5/16” hose and manometer over the tapered outlet pressure boss on the valve (see figure below). If regulator needs to be adjusted, see instructions below.
