Automatic chemical dosing devices are usually more efficient in heater water, unless controlled, they can lead to excessive chlorine level which can damage your heater.

CAUTION: The XTherm is not for use with salt water chlorinators—damage to heater may occur.

Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical suppli- er for the correct levels for your water.

Water Hardness

Raypak water heaters can operate lime/scale-free using potable water with a hardness not exceeding 25 gpg for models 1005 and 1505, and not exceeding 16 gpg for model 2005. Proper operation is achieved by setting the temperature rise/water flow per the guide- lines in the installation instructions. If the hardness of the water exceeds the maximum level of 25 gpg spe- cial measures must be taken to lower it. Water should be softened to a hardness level no lower than 5 gpg. Water softened as low as 0 to 1 grain per gallon may be under-saturated with respect to calcium carbonate resulting in water that is aggressive and corrosive.

NOTE: Soft = 0–4 grains per gallon; Medium = 5–15 grains per gallon; Hard = 16–25 grains per gallon.

NOTE: Failure of a heat exchanger due to lime scale build-up on the heating surface, low pH or other chemical imbalance is non-warrantable.

Gas Supply

DANGER: Make sure the gas on which the heater will operate is the same type as specified on the heater’s rating plate.

Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shut-off valve lo- cated outside the heater jacket. It is recommended that a union be installed in the gas supply piping adja- cent to the heater for servicing. The gas supply pressure to the heater must not exceed 10.5 in. WC for natural gas or 13.0 in. WC for propane gas.

A pounds-to-inches regulator must be installed to reduce the gas supply pressure if it is higher than noted above. This regulator should be placed a mini- mum distance of 10 times the pipe diameter upstream

of the heater gas controls. Refer to Table J on page 20 for maximum pipe lengths.

Gas Supply Connection

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 upstream manual shut-off valve 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 re-connecting the heater and its manual shut-off valve to the gas supply line. FAILURE

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

Fig. 18: Gas Supply Connection

CAUTION: Do not use Teflon tape on gas line pipe thread. A pipe compound rated for use with natural and propane gases is recommended. Apply sparingly only on male pipe ends, leaving the two end threads bare.

CAUTION: Support gas supply piping with hangers, not by the heater or its accessories. Make sure the gas piping is protected from physical damage and freezing, where required.
