Torus Stainless Steel Condensing Boilers & Water Heaters – Installation Manual
OUTDOOR VENTING
When installed outdoors the Torus Line must be fitted
with the factory supplied outdoor hood, air intake
adapter with filter and exhaust terminal, see Figure 7.
Multiple units must be spaced per Figure 8.
The boiler/heater must be at least
2 ft, .62 m from any
door, window or gravity air inlet into any building and at
least
3 ft, 1 m from any overhang unless local codes
dictate differently.
Avoid locations where wind deflection off of adjacent
walls, buildings or shrubbery might cause a downdraft.
The unit(s) should be located at least 3 ft, 1 m from
structures. Outdoor installations are not recommended
in areas where the danger of snow blockage exists.
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!

Outdoor Installations
The Torus Boiler/Water Heater is certified for
outside installations in temperate climates
only.
1. The condensate traps located under the secondary
heat exchanger and the vent pipe must be wrapped
with heat tape to ensure the traps never drop below
32°F.
2. The vent pipe must be insulated to prevent freezing
of condensate in the pipe.
3. The boiler and system must be filled with a
polypropylene glycol/water antifreeze mixture not
to exceed 50% glycol by volume.
4. All water piping exposed to low temperatures must
be insulated.
