Contamination Prevention; Venting Application; Boiler Room Air Supply And Ventilation - Slant/Fin Jaguar J-390 Installation And Operating Instructions Manual

Jaguar Model J-390

CONTAMINATION PREVENTION

The combustion air supply must not be susceptible to contami-
nation sources, whether the combustion air comes from the
interior or exterior of the building. Contaminated air can cause
corrosion or other damage to the heat exchanger and compo-
nents of the boiler, causing failure of these parts or unsafe
operation.
Below is a list of products and areas which may cause
contaminated combustion air:
PRODUCTS TO AVOID
• Spray cans containing chloro/fluorocarbons
• Permanent wave solutions
• Chlorinated waxes/cleaners
• Chlorine-based swimming pool chemicals
• Calcium chloride used for thawing
• Sodium chloride used for water softening
• Refrigerant leaks
• Paint or varnish removers
• Hydrochloric acid/muriatic acid
• Cements and glues
• Antistatic fabric softeners used in clothes dryers
• Chlorine-type bleaches, detergents, and cleaning
solvents found in household laundry rooms
• Adhesives used to fasten building products and other
similar products
AREAS LIKELY TO HAVE CONTAMINANTS
• Dry cleaning/laundry areas and establishments
• Swimming pools
• Metal fabrication plants
• Beauty shops
• Refrigeration repair shops
• Photo processing plants
• Auto body shops
• Plastic manufacturing plants
• Furniture refinishing areas and establishments
• New building construction
• Remodeling areas
• Garages with workshops

VENTING APPLICATION

The Jaguar J-390 is a sealed combustion type boiler, it may be
installed and vented either as a direct vent boiler which all air
for combustion is obtained directly from outside or as a non-
direct vent boiler which air for combustion is taken from inside
the boiler room.
The Jaguar J-390 boiler must be vented by 4" diameter
PVC/CPVC schedule 40 pipe, or the proper 4" diameter stain-
less steel venting system (see "vent material" on page ???)
through the roof or sidewall.

BOILER ROOM AIR SUPPLY AND VENTILATION

An ample supply of air is required for combustion and ventila-
tion. When buildings are insulated, caulked and weather-
stripped, now or later on, direct openings to outside may be
required and should be provided. If the boiler is not near an
outside wall, air may be ducted to it from outside wall openings.
Provisions for combustion and ventilation air must be made in
accordance with section 5.3, Air for Combustion and Ventila-
tion, of the National Fuel Gas Code, ANSI Z223.1-latest edi-
tion, or applicable provisions of the local building codes. The
following recommendation applies to buildings of energy-saving
construction, fully caulked and weatherstripped.
INSTALLATION IN ENCLOSED BOILER ROOM REQUIRES
TWO UNOBSTRUCTED OPENINGS FOR PASSAGE OF AIR
INTO THE BOILER ROOM.
A. NON-DIRECT VENT INSTALLATION
1. Air drawn horizontally from outdoors DIRECTLY
through an outside wall; one louvered opening near the
floor and one louvered opening near the ceiling, each
opening with a minimum FREE air passage area of 1
square inch per 4000 Btuh of total appliances' input.
2. Air drawn horizontally through HORIZONTAL DUCTS;
one opening near the floor and one opening near the ceil-
ing, each opening with a minimum FREE air passage area
of 1 square inch per 2000 Btuh of total appliances' input.
3. Air drawn VERTICALLY from outdoors; one opening at
the floor and one opening at the ceiling, each opening with
a minimum FREE air passage area of 1 square inch per
4000 Btuh of total appliances' input.
4. Air drawn from inside the building; one opening near
the floor and one opening near the ceiling, each opening
with a minimum FREE air passage area of 1 square inch
per 1000 Btuh of total appliances' input.
IF BOILERS ARE INSTALLED ADJACENT TO OTHER FUEL
BURNING EQUIPMENT, THE AREA OF FREE OPENINGS
MUST BE APPROPRIATELY INCREASED TO ACCOMMO-
DATE THE ADDITIONAL LOAD.
B. DIRECT VENT INSTALLATION
Adequate air supply should be provided to prevent overheating
of the boiler controls and boiler room. Openings for passage of
air into the boiler room for direct-vent installation must be at
least 1 ⁄ of the openings required for the non-direct vent as
2
mentioned above.
If additional non-direct vent appliances are installed in the
same space and adequate air openings are provided for them,
there are no additional air openings required for the Jaguar
J-390 boiler.
