The Valiant FT Series II does not necessarily require
access through the sides and can be placed adjacent to
each other with minimum clearances. However, it is highly
recommended to allow for at least a minimum clearance of
10” on the appliance’s right-hand side. This allows for easy
access to maintain the combustion air filter. Access panels
from the sides of the unit are also provided to make the
appliance more accessible for easier maintenance. This
provides larger points of access for greater ease of
serviceability.
The appliance should be located close to a floor drain in an
area where leakage from the appliance or connections will
not result in damage to the adjacent area or to lower floors
in the structure. Under no circumstances is the
manufacturer to be held responsible for water damage in
connection with this unit or any of its components.
Do not locate this appliance in an area where it will be
subject to freezing unless precautions are taken. Due to low
jacket losses from the appliance, radiant losses from the
boiler are minimal and should not be relied on to keep the
appliance room warm. Supplemental heat may be required
in the boiler room to maintain ambient temperature at
acceptable levels.
Do not locate this appliance where it may be exposed to a
corrosive atmosphere.
Low Water Cut-Off requirement : If the appliance is
installed above the level of the building’s radiation system,
a low water cut-off device must be installed in the appliance
outlet at some distance above the heat exchanger
inlet/outlet connections. A port for a LWCO probe is
provided on the outlet piping, inside the jacket, of this
appliance. Some local codes require the installation of a low
water cut-off on all systems.
2.2 COMBUSTION AIR AND VENTILATION
DANGER
It is extremely important to follow these venting
instructions carefully. Failure to do so can cause severe
personal injury, death or substantial property damage.
A continuous supply of combustion air must be
provided at all times for the safe operation of this
appliance!
The Valiant-FT is a Category II and Category IV appliance.
A Category IV appliance is individually vented through a
dedicated vent. The Combustion air may be drawn from the
room. However, in the case the boiler is direct vented, the
combustion air must also be piped directly to the outdoors.
The Valiant FT boiler utilizes Category IV Venting, capable
of venting up to a combined 200’ equivalent length of vent
(maximum 100’ of exhaust and a 100’ of combustion air
intake vent). This appliance may only use approved venting
(see table below).
For direct vent applications, the wall thickness must be
between 0.5” – 12” (1.2 cm to 30 cm).
Some of the different venting configurations include:
