OUTDOOR VENTING

When installed outdoors the Spectrum must be fitted
with the factory supplied outdoor hood assembly, see
Figure 3. Multiple units must be spaced per Figure 3A.
The boiler/water heater must be at least 10 ft, 3.1 m
from any door, window or gravity air inlet into any
building and at least 3 ft, 0.9 m from any overhang
unless local codes dictate differently.
Avoid locations where wind deflection off of adjacent
walls, buildings or shrubbery might cause a down draft.
The unit(s) should be located at least 3 ft, 0.9 m from
structures. Outdoor installations are not recommended
in areas where the danger of snow blockage exists.
CAUTION: Do not place the boiler/water heater in a
location that would subject it to runoff from adjacent
buildings or damage may occur voiding the
warranty!

GENERAL PIPING REQUIREMENTS

CAUTION: Improper piping of this boiler/water
heater will void the manufacturer's warranty and can
cause boiler failure resulting in flooding and
extensive property damage! Excessive water
hardness causing lime build-up in the copper heat
exchanger tubes is NOT covered under the
manufacturer's warranty. Excessive pitting and
erosion of the internal surface of the copper heat
exchanger tubes is NOT covered under the
manufacturer's warranty if the result of high water
flow rates, see Table 7 or 8. Return water
temperatures below 110°F, 43 ° C will result in heat
exchanger damage from excessive condensation
voiding the manufacturer's warranty, see Primary/
Secondary Piping Figure 5.
NOTE: Shut off valves and unions should be installed
at the inlet and outlet connections of the boiler wa-
ter heater to provide for isolation of the unit should
servicing be necessary.
Freeze Protection
This boiler/water heater is CSA designed certified for
outdoor installation. Outdoor installations in areas where
the danger of freezing exists are not recommended
unless proper freeze protection is provided. If the unit
is to be installed in such an area the following
precautions MUST be observed:
1. A continuous flow of water through the boiler/water
heater MUST be maintained! The pump responsible
for flow 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 15% more flow 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 boiler/water heater 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.
CAUTION: Improper outdoor installation of this
boiler/water heater can cause boiler failure voiding
the manufacturer's warranty!
