Raypak 850, 300 Installation Codes, Equipment Base, Clearances, Indoor Installations

INSTALLATION

Installation Codes

Installations must follow these codes:

•Local, state, provincial, and national codes, laws, regulations and ordinances

•National Fuel Gas Code, ANSI Z223.1/NFPA 54 – latest edition (NFGC)

•National Electrical Code, ANSI/NFPA 70 - latest edition (NEC)

•Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1, (CSD-1) when required

•For Canada only: CAN/CSA B149 Natural Gas and Propane Installation Code and CSA C22.1 C.E.C. Part 1 (C22.1)

Equipment Base

The heater must be mounted on a level, structurally sound surface. The heater is approved for installation on a combustible surface but must NEVER be installed on carpeting. Gas-fueled equipment installed in enclosed parking garages must be located at least 18 in. above the floor.

CAUTION: The boiler must be level to allow condensate to drain properly from the heat exchanger.

CAUTION: This boiler should be located in an area where water leakage will not result in damage to the area adjacent to the appliances or to the structure. When such locations cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the appliance. The pan must not restrict air flow.

In addition, the heater shall be installed such that the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation or service (circulator replacement, control replacement, etc.).

If the heater needs to be secured to the ground, use the holes in the anchoring legs on the heater.

*DO NOT install on carpeting.

Table D: Clearances — Indoor Installations

When installed according to the listed minimum clear- ances from combustible construction, these heaters can be serviced without removing permanent structur- al construction around the heater. However, for ease of servicing, we recommend a clearance of at least 24 in. in front, at least 24 in. on the rear and 24 in. above the top of the heater. This will allow the heater to be serviced in its installed location without movement or removal of the heater.

Service clearances less than the minimum may require removal of the heater to service either the heat exchanger or the burner components. In either case, the heater must be installed in a manner that will enable the heater to be serviced without removing any structure around the heater.

Outdoor Installations

These heaters are design-certified for outdoor installa- tion. Heaters must not be installed under an overhang unless clearances are in accordance with local instal- lation codes and the requirements of the gas supplier. Three sides must be open in the area under the over- hang. Roof water drainage must be diverted away from heaters installed under overhangs.
