appliance to allow condensate to be evacuated at the drain tee.
Plastic drain tubing, sized per the vent manufacturer’s
instructions, shall be provided as a drain line from the tee and
from the boiler condensate line. The drain tubing from the tee
must have a trap provided by a 4" (10cm)-diameter circular trap
loop in the drain tubing and the boiler drain shall be normal with
no loop and tied into the tee drain tubing with a tee at a point
after the 4" loop and before the neutralizer. Prime the trap loop
by pouring a small quantity of water into the drain hose before
assembly to the vent. Secure the trap loop in position with nylon
ties. Use caution not to collapse or restrict the condensate drain
line with the nylon wire ties. The common condensate drain must
be routed to the condensate neutralization system or a suitable
drain for disposal of condensate that occurs in both the boiler
and in the vent system. Ensure that the drain from the
condensate tee is not exposed to freezing temperature.
2.2 CONVENTIONAL VENTING (INDOOR)
INSTALLATIONS
•
The Dynaforce® is a category II appliance and is approved
for venting into a common Chimney. On single appliance
installations with dedicated chimney, if drafts are excessive
(above negative 0.15 Inches W.C.), we recommend a single
acting barometric damper.
• A qualified professional using a proven vent-sizing program
with input of accurate operating parameters must properly
do sizing of the venting system. In applications where flue
gas temperatures are lower than can support a Category II
with conventional negative draft, it will be determined at the
venting design stage that a positive pressure will be
developed in the vent. It will then be necessary to either
provide separate vents as for Category IV, pressurize the
room or to provide an extractor at the chimney outlet
interlocked with the appliance operating circuit in order to
maintain a negative draft in the chimney and allow common
venting.
•
Approval of the installation will be at the discretion of
authorities having jurisdiction.
IN GENERAL
•
The operation of exhaust fans, compressors, air handling
units etc. can rob air from the room, creating a negative
pressure condition leading to reversal of the natural draft
action of the venting system. Under these circumstances an
engineered air supply is necessary.
• If the appliance is to be installed near a corrosive or
potentially corrosive air supply, the appliance must be
isolated from it and outside air should be supplied as per
code.
• Potentially corrosive atmospheres will result from exposure
to permanent wave solution, chlorinated waxes and
cleaners, chlorine, water softening chemicals, carbon
tetrachloride, halogen based refrigerants, Freon cleaning
solvents, hydrochloric acid, cements and glues, masonry
washing materials, antistatic fabric softeners, dry cleaning
solvents, degreasing liquids, printing inks, paint removers,
etc.
• The equipment room MUST be provided with properly sized
openings to assure adequate combustion air and proper
ventilation when the unit is installed with a proper venting
system.
2.2.1 AIR REQUIRED FOR COMBUSTION AND
VENTILATION
Provisions for combustion and ventilation air are to be in
accordance with the section for “Air for Combustion and
Ventilation”, of the National Fuel Gas Code, ANSI Z223.1/NFPA
54, or clause 8.2, 8.3, 8.4 of “Natural Gas and Propane
Installation Code”, CAN/CSA B149.1.2, or applicable provisions
of the local building codes.
If air is taken directly from outside the building with no duct,
provide two permanent openings:
a) Ventilation of the space occupied by fuel burning
appliance(s) or equipment shall be supplied by a ventilation
opening at the highest practicable point communicating with
the outdoors. The total cross sectional area of the
ventilation opening must be either 10% of the net free area
required for combustion air or 10 sq. in (6500 mm
2
),
whichever is greater.
b) Net free area of combustion air opening shall be in
accordance with all applicable codes. In the absence of
such codes provide combustion air opening with a minimum
free area of one square inch per 7,000 Btuh input (5.5 cm
per kW) up to 1,000,000 Btuh and one square inch per
14,000 Btuh in excess of 1,000,000 Btuh. This opening
must be ducted no higher than 18” nor less than 6” above
the floor.
c) In extremely cold climates when air supply is provided by
natural air flow from the outdoors we recommend sizing the
combustion air supply opening with a minimum free area of
not less than one square inch per 30,000 Btu/hr, of the total
rated input of the burner, provided that this does not conflict
with local codes. This opening is in addition to the
ventilation opening defined in paragraph a) above.
NOTE
Outside air openings shall directly communicate with the
outdoors.
CAUTION
Under no circumstances should the mechanical room ever
be under a negative pressure. Particular care should be
taken where exhaust fan, attic fans, clothes dryers,
compressors, air handling units, etc., may take away air from
the unit.
2.2.2 EXHAUST FANS
Any fan or equipment which exhausts air from the equipment
room may deplete the combustion air supply and/or cause a
downdraft in the venting system through a barometric damper if
installed. Spillage of flue products from the venting system into
an occupied living space can cause a very hazardous condition
that must be immediately corrected.
2.3 OUTDOOR VENTING
The Dynaforce® windproof cabinet protects the unit from
weather, when fitted with the factory supplied air intake and UL
approved vent cap (93-0298), it will be self-venting and suitable
for outdoor installation.
1. Outdoor models must be installed outdoors and must use
the air intake and vent cap supplied by Camus® Hydronics.
2. Periodically check to ensure that air intake and vent cap are
not obstructed.
3. Locate appliance at least 3 feet away from any overhang.
4. Locate appliance at least ten feet from building air intake.
5. Avoid installation in areas where runoff from adjacent
building can spill onto appliance.
For outdoor installations, always consider the use of a shelter
such as a garden shed in lieu of direct exposure of the appliance
to the elements. The additional protection afforded by the shelter
will help to minimize nuisance problems with electrical
