HOT WATER OUTLET
- The hot water outlet joint is ½" NPT pipe thread.
- The hot water outlet should be connected by exible tubing or rigid PVC of the type
intended for use with hot water.
- The inner diameter of the water outlet pipe (including the valve) shouldn't be less
than 3/8". Larger diameter pipe is acceptable as long as the appropriate adapters are
used.
- After connecting, fully open the cold water supply to conrm the ow of water and to
check for leaks. Correct leaks as necessary.
INSTALLING THE GAS SUPPLY
The gas inlet joint is ½" NPT pipe thread. Very Important: Use Teon tape for gas or gas
pipe paste between the unit and the gas inlet pipe connector.
- For small bottle Liquid Propane installations: Connect the gas supply to your propane
bottle using a standard rubber Liquid Propane hose and low pressure regulator. Opti-
mal pressure for your unit is .41-.5 PSI, the same as a typical gas grill. Pressures set
outside this range may result in inconsistent behavior from your water heater.
- For whole house Liquid Propane or Natural Gas Installations: The unit should be con-
nected directly to the home gas supply using black iron gas pipe or the braided metal
gas appliance hoses located in the water heater section of your local home improve-
ment store. WARNING: THIS TYPE OF CONNECTION MUST BE MADE BY A PROFESSION-
AL. Please note that Natural Gas units require .25-.5 PSI for your unit to operate correct-
ly. If you are unsure of your gas pressure, contact your gas company.
After the gas inlet is connected, open the gas supply valve and check for gas leaks at all
connections by spraying with soapy water and watching for bubbles. Do not skip this
step! Adjust or repair leaks as needed.
- All gas connections must be made in accordance with local building codes and regu-
lations.
INSTALLING THE EXHAUST PIPE
WARNING! There is water contained in the coils of your water heater at all times. If your
water heater is exposed to freezing temperatures, the water in the coils could freeze,
causing a break in the heat exchanger of the unit.
