All Raypak heaters are National Board Approved, and design-certified and tested by the Canadian Stan- dards Association (CSA) for the U.S. and Canada. Each heater is constructed in accordance with Section IV of the American Society of Mechanical Engineers (ASME) Pressure Vessel Code, and bears either the ASME “H” stamp for boilers or “HLW” stamp for water heaters. The heater also complies with the latest edi- tion of ASHRAE 90.1 Standard.

WARNING: Altering any Raypak pressure vessel by installing replacement heat exchangers, tube bundle headers, or any ASME parts not manufac- tured and/or approved by Raypak will instantly void the ASME and CSA ratings of the vessel and any Raypak warranty on the vessel. Altering the ASME or CSA ratings of the vessel also violates national, state, and local approval codes.

Rated inputs are suitable for up to 4,500 ft elevation without de-rating. Consult the factory for installations at altitudes over 4,500 ft above sea level.

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)

For Canada only: CAN/CGA B149 Installation Code (B149.1) and CSA C22.1 C.E.C. Part 1 (C22.1)

Gas Supply

This heater will be connected to 2 different gas sup- plies (Natural Gas and Propane Gas).

Each gas piping must have a separate sediment trap ahead of the gas controls. Pounds-to-inches regula- tors must be installed to reduce the gas supply pressure to a maximum of 10.5 in. WC for natural gas and 13.0 in. WC for propane gas. The regulator should be placed a minimum distance of 10 times the pipe diameter upstream of the heater gas controls.

CAUTION: The heater must be disconnected from the gas supply during any pressure testing of the gas supply system at test pressures in excess of 1/2 psi (3.45 kPa).

The heater must be isolated from the gas supply pip- ing system by closing the manual shut-off valves during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.45 kPa). Relieve test pressure in the gas supply line prior to reconnecting the heater and its manual shut-off valves to the gas supply lines. FAILURE TO FOLLOW

THIS PROCEDURE MAY DAMAGE THE GAS VALVES. Over-pressurized gas valves are not cov- ered by warranty. The heater and its gas connections shall be leak-tested before placing the appliance in operation. Use soapy water for leak test. DO NOT use an open flame.
