Lochinvar COPPER-FIN II CF-1261, Руководство дизайнера

Страница: 19 / 32

The combustion air inlet of the outdoor cap
must be located at least one foot (0.30m)
above grade and above normal snow levels.
The water heater
must be at least 10 feet
(3.05m) away from any forced air inlet and
at least 3 feet (0.91m) outside any overhang.
Do not install in locations where rain from
building runoff drains will spill onto the
water heater.
Lochinvar must furnish an outdoor vent kit
in accordance with CSA international
requirements. Each kit includes the flue
outlet/combustion air inlet, assembly, gasket
and pump cover.
Freeze Protection-
Outdoor Installation
A snow screen should be installed to prevent
snow and ice accumulation around the
appliance or its venting system.
If for any reason the unit is to be shut off:
(a.) Shut off water supply.
(b.) Drain unit completely.
(c.) Drain pump and piping.
If freeze protection is not provided for the
system, a low ambient temperature alarm or
automatic drain system is recommended.
GAS SUPPLY
The gas pressure regulator supplied is for
low pressure service. If upstream pressure
exceeds 6 oz. (10.5" water column), an
intermediate gas pressure regulator, of the
lock up type,
must be installed.
The gas line should be a separate line
direct from meter, unless the existing
gas line is of sufficient capacity. Verify
pipe size with your gas supplier.
