Figure 11 Corrosive contaminants and sources
Do not install the Ultra boiler into a common vent with
any other appliance. is will cause ue gas spillage or ap-
pliance malfunction, resulting in possible severe personal
injury, death or substantial property damage.
Existing common vent systems may be too large for the
appliances remaining connected aer the existing boiler
is removed.
Failure to follow all instructions can result in ue gas
spillage and carbon monoxide emissions, causing severe
personal injury or death.
Use ONLY the venting materials and venting manufac-
turers’ components and systems approved by WM Tech-
nologies. Follow all instructions provided by the venting
component and system manufacturer. Failure to do so can
cause ue gas spillage and carbon monoxide emissions,
resulting in severe personal injury or death.
The Ultra boiler cannot be common vented with any other appli-
ance
. When an existing boiler is replaced with an Ultra boiler, the Ultra
boiler CANNOT use the existing common vent. e Ultra boiler requires
its own vent and air piping, as specied in this manual. is may cause a
problem for the appliances that remain on the old common vent, because
the vent may be too large.
Perform the test sequence below for each appliance remaining on the
original common vent system. Operate each appliance individually with
other appliances turned o. is procedure will test whether the common
vent system can properly vent each appliance.
(The following is intended to test whether the appliances remaining on an
existing vent system will operate satisfactorily.)
1. Visually inspect the venting system for proper size and horizontal pitch
and determine there is no blockage or restriction, leakage, corrosion or
other deciencies which could cause an unsafe condition.
2. Test vent system — Insofar as is practical, close all building doors and
windows and all doors between the space in which the appliances
remaining connected to the common venting system are located and
other spaces of the building. Turn on clothes dryers and any appliance
not connected to the common venting system. Turn on any exhaust
fans, such as range hoods and bathroom exhausts, so they will oper-
ate at maximum speed. Do not operate a summer exhaust fan. Close
replace dampers.
3. Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust thermostat so appliance will operate continuously.
4. Test for spillage at dra hood relief opening aer 5 minutes of main
burner operation. Use the ame of a match or candle, or smoke from
a cigarette, cigar, or pipe.
5. Aer it has been determined that each appliance remaining connected
to the common venting system properly vents when tested as outlined
herein, return doors, windows, exhaust fans, replace dampers, and
any other gas-burning appliance to their previous conditions of use.
Any improper operation of common venting system should be corrected so
the installation conforms with the National Fuel Gas Code, ANSI Z223.1
— latest edition. Correct by re-sizing to approach the minimum size as
determined using the appropriate tables in Part13 of that code. Canadian
installations must comply with B149.1 or B149.2 Installation Code.
Products to avoid
Spray cans containing chloro/uorocarbons
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
Excessive dust and dirt
You must provide combustion air.
Direct vent — Install air inlet piping for the Ultra
boiler as described in the Boiler manual and this ad-
dendum. e air termination tting must be installed
with the clearances and geometry relative to the vent
outlet depicted in this manual to ensure that ue
products do not enter the air intake.
Direct exhaust — Provide combustion air openings
to boiler room/building as specied in this adden-
dum and as required by all applicable codes.
Ensure that the combustion air will not contain
any of the contaminants in Figure 11
. DO NOT
place combustion air supply opening or intake near
a swimming pool, for example. Avoid areas subject
to exhaust fumes from laundry facilities. ese areas
will always contain contaminants.
Contaminated combustion air will damage the boiler,
resulting in possible severe personal injury, death or
substantial property damage.
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 renishing areas and establishments
New building construction
Remodeling areas
Garages with workshops
Buildings under construction (where air is contaminated
with particulates)
