NOTE:
Experience has shown that improper installation or
system design, rather than faulty equipment, is the
cause of most operating problems
1.10 BOILER ROOM OPERATING CONDITION
•
Due to low jacket losses from the appliance,
temperatures in a typical boiler room may drop
significantly; supplemental heat is required to maintain
ambient temperature at acceptable levels.
•
Cold fresh air intakes must be located to minimize the
effects on venting and subsequent condensation in the
flue of Category I installations. When necessary,
consider the use of insulation or corrosion resistant
venting material.
•
Camus® DynaFlame® boilers and water heaters are
approved at 85% efficiency which allows the
equipment to be vented as a Category I appliance
using either single wall “C” vent or double wall “B” vent.
Certain conditions in the field however lead to
condensation in the vent and render these products
unsuitable.
These conditions include and are not necessarily limited to:
1. Low boiler room temperature.
2. Low return water temperature.
3. Long periods of low fire operation.
4. Oversized breeching in common venting
applications.
5. Proximity to combustion air openings.
Given the frequency of these conditions occurring in the
field, we are recommending the use of corrosion resistant
stainless steel venting wherever possible.
1.11 CLEARANCE FROM COMBUSTIBLE
MATERIAL
This appliance is suitable for alcove (a closet without a
door) installation with minimum clearances to combustibles
as follows:
Table 1: Clearances from Combustibles
Clearances from Combustibles
TOP: 12”
SIDES: 12”
REAR: 12”
VENT: 6”
Figure 4: Clearance from Combustibles
When placing the appliance be aware that a minimum
clearance of 24” (60cm) must be provided at the front to
allow easy access to the primary heat exchanger.
NOTE: Clearances from combustible construction are
noted on the appliance rating plate
When installed directly on combustible flooring, the
appliance shall be installed on a metal panel extending
beyond the full width and depth of the appliance by at least
3 inches (76.2mm) in any direction. The floor must be
strong enough to support the full weight of the heater.
Maintain minimum specified clearances for adequate
operation. All installations must allow sufficient space for
servicing the vent connections, water pipe connections,
circulating pump, bypass piping and other auxiliary
equipment, as well as the appliance
