FUTERA II INSTALLATION AND OPERATION INSTRUCTIONS
NOTE: Shut off valves and unions should be installed
at the inlet and outlet connections of the boiler/hot
water heater to provide for isolation of the unit should
servicing be necessary.
Freeze Protection
This boiler/water heater is CSA designed certifi ed for out-
door installation. Outdoor installations in areas where the
danger of freezing exists are not recommended unless
proper freeze protection is provided. The following
precautions MUST be observed:
1. A continuous fl ow of water through the unit MUST be
maintained! The pump responsible for fl ow through the
boiler/water heater must run continuously!
2. An ethylene glycol/water mixture suitable for the
minimum temperature that the unit will be exposed to
must be used. The pump must be capable of producing
a minimum of 15% more fl ow and overcoming a 20%
increase in head loss. Domestic water systems must be
isolated from the water heater by the use of a heat
exchanger or other approved method.
3. If the unit must be shut off for any reason the electric,
gas and water supplies MUST be shut off and the unit
and its pump completely drained.
