Triton │Installation and Operation Instructions - Natural Draft VS80-130
10
5.0 GENERAL VENTING
Triton boilers are certified as Natural Draft appliances. ANatural Draft installation draws combustion air from the
room and uses the stack effect and draft system to exhaust flue gases using a chimney.
Air Supply - Allowances for combustion air must be supplied to the appliance space, due to the fact that the
heating appliance consumes large volumes of combustion air. In most instances, a permanent opening with an
unobstructed or “free area” of 1 square inch for every 1000 BTU’s of input will provide a sufficient amount of
combustion air for the boiler to operate properly. If the building is fairly new and relatively air tight,
compensate for the air tightness by using a “free area” that is 15% larger that what was calculated above. Do
not place the boiler in, or adjacent to, a room where an exhaust fan is operating. Refer to “Combustion Air”
section for more details. Installation must comply with Standard CSA B139 (Canada) and NFPA 31 (USA).
Stack Draft - Sufficient draft by natural or mechanical means is necessary for ensuring optimal and consistent
operation. The appliance should have a stack draft sufficient to support stable operation. See Draft Settings.
Avoiding Condensation - Due to the high combustion efficiencies and low stack gas
temperatures, great care must be taken to ensure that the chimney isn’t subjected to gas
condensation. The exhaust gas temperature where the flue pipe enters the chimney must
be a minimum of 240oF or condensation may occur.
Draft Regulator - A draft regulator must be used and set to regulate the draft of the boiler. Make sure that the
damper is free to operate without sticking, for this will affect the boiler’s combustion system. It is important
that the draft be adequate because poor draft conditions will cause poor operation and a possible hazardous
condition.
Draft Settings –The Triton is designed to operate with a -0.04” w.c. draft in the flue
breaching; therefore, ensure there is enough natural or mechanical draft for proper
operation. Due to the design of the Triton it may operate at a positive over fire pressure
up to +0.03 at a -0.02 draft.
Natural Draft Rules and Guidelines
1. Acceptable Venting Material - Use vent material approved by National Standards NFPA 31 (USA) or CSA
B139 (Canada) and local codes.
2. Venting Application - Venting must be connected to a chimney for models operating with Natural Draft.
3. Chimney Condition - Inspect existing chimney before installing new boiler. Deterioration of mortar joints
should be repaired prior to using.
4. Chimney Height - Chimney must extend 3’ above the highest point where it exits the roof and 2’ higher than
any part of the structure within 10’.
5. Cleaning - Clean chimney, if required; ensure it is clear of any blockages before connecting breeching.
6. Liner Condition - Damaged liner or pipe should be repaired before commencing installation.
7. Minimum Clearances - Observe clearances to combustibles illustrated in Figure 3-1 and Table 3-1:
8. a) Double-wall vent (Type-L) 6"
9. b) Single-wall vent 9"
10. Chimney Sizes - Minimum chimney sizes should be used. See Table 5-1.
11. Combustion Air - An adequate supply of combustion air must be available to ensure proper combustion.
12. Interlock - If a damper is used to provide make-up air for combustion, it must be interlocked with the burner
to prevent the burner starting before the damper is opened.
Potential Condensation - Oversized chimneys, outside masonry chimneys, and/or de-
rated inputs can result in flue gases condensing in the chimney.

VS80-130 Natural Draft - Installation & Operation Instructions │Triton
11
Combustion Air
Natural Draft appliances require an adequate amount of combustion air to sustain proper combustion and prevent
flue gas leakage. The appliance’s air-inlet draws combustion air from Indoors or Outdoors depending on whether
there is a sufficient natural infiltration (air changes) occurring to sustain combustion. If the building is newer and
relatively air tight, outdoor air should be considered. For recommended practice, refer to NFPA 31 (USA) or
CSA B139 (Canada).
Air Circulation - The boiler shall be located so as not to interfere with proper circulation
of combustion, ventilation, and dilution air.
Make-up Air - The operation of exhaust fans, kitchen ventilation systems, clothes dryers,
and fireplaces must be considered in determining the adequacy of a space to provide
combustion air requirements. Failure to ensure adequate make-up air to all appliances
may result in flue gas leakage, personal injury or death.
Permanent Openings for Combustion Air
The appliance space or boiler area requires a permanent opening(s) capable of providing adequate combustion air
to the boiler. If using two permanent openings, one opening must be within 12 inches of the ceiling, the other
within 12 inches of the floor. The minimum dimension of air openings to the appliance space shall not be less
than 3 inches in any one direction, including rectangular ducts. Round ducts are connected to the permanent air
openings; duct sizes must have a minimum cross-sectional area of 3 inches. See “Sizing Combustion Air
Openings” for more details.
The minimum size of permanent openings and how combustion air is supplied to them depends on three factors:
1. What is the input capacity of the boiler in Btu/hr?
2. How is the Combustion Air being supplied?
3. Is make-up air required for other appliance in the room competing for the same air?
Sizing Combustion Air Openings
The following sections detail the three (3) methods for determining the minimum opening size and location
required for providing combustion air:
1. Indoor Air - Opening Sizes: Older buildings typically have sufficient ventilation due to air leakage around
single pane windows, poorly weather-stripped doors, and non-existent vapour barrier. Indoor air can be used
to supply combustion air to the boiler area if the air infiltration rate is adequate, i.e. greater than 0.4 ACH (air
changes per hour) or when the boiler area and communicating spaces have a minimum volume of 50 cubic ft
per 1000 Btu/hr. If the air infiltration rate is known to be less that 0.4 ACH, refer to the Installation Code for
Oil-Burning Equipment for further guidance.
a. Combined spaces on the same story
minimum free area of openings = 1 in.2/1000 Btu/hr of total input rating of all appliances in the space.
not less than 100 sq. in.
two openings required - one within 12 in. from ceiling, other within 12 in. from floor or bottom of the
enclosure.
minimum dimension of air openings shall be not less than 3 in.
b. Combined spaces in different stories
Volume of spaces in different stories shall be considered as communicating spaces where spaces
connected by one or more openings in doors or floors having a total minimum free area of 2 in.2/1000
Btu/hr of total input rating of all appliances.

Triton │Installation and Operation Instructions - Natural Draft VS80-130

2. Outdoor Air - Opening Sizes: When outdoor air is used to supply combustion air to the appliance space,
both openings must connect directly to the outdoors via ducts or connect to a crawl space or attic that
connects freely to the outdoors. Outdoor combustion air provided through opening(s) to the outdoors must be
made in accordance with the methods detailed below.
a. Two Permanent Openings Method - Two permanent openings shall be provided, one commencing
within 12 in. of the top, and the other within 12 in. of the bottom of the enclosure. The openings shall
communicate directly, or by ducts, with the outdoors or spaces that freely communicate with the
outdoors, as follows:
vertical ducts, minimum free area =1 in.2/4000 Btu/hr of total input rating of all appliances in the
space.
horizontal ducts, minimum free area =1 in.2/2000 Btu/hr of total input rating of all appliances in the
space.
b. One Permanent Opening Method - One permanent opening, commencing within 12 in. of the top of
the enclosure, shall be provided. The appliance shall have clearances of at least 1 in. from the sides and
back and 6 in. from the front of the appliance. The opening shall directly communicate with the outdoors
or shall communicate through a vertical or horizontal duct to the outdoors or spaces that freely

Connect Breeching & Blocked Vent Switch
Restrictions - Use the minimum vent length and number of elbows possible to ensure
flow of combustion gases are not restricted. Failure to follow instructions may result in
severe personal injury or death.
Blocked Vent Switch - For complete installation details, refer to the manufacturer’s
instructions included with the Blocked Vent Switch.
The steps for connecting breeching to a chimney are illustrated in Figure 5-1 and should be read in conjunction
with the sizes specified in Table 5-1. Restricted flow can result in condensation, flue gas leakage, and/or carbon
monoxide emissions.
Breeching Installation:
1. Chimney Clearances –Observe clearances to combustibles for breeching and chimney connections.
2. Supports –Install flue pipe brackets according to local codes or as needed.
3. Breeching Sizes –Connect breeching to the boiler flue collar. Use full size breeching when possible. Refer to
Table 5-1 for minimum sizes.
4. Potential Restrictions –Keep breeching lengths and elbow-tee combinations to a minimum to avoid
restricting the flow of combustion gases. See warning titled “Restrictions”.
5. Chimney Connections –Use thimble or slip joint where breeching enters chimney to allow for removal for
cleaning and servicing.
6. Avoiding Obstructions –Ensure breeching does not protrude so far into the chimney that it will cause
obstruction. Avoid connecting near the bottom of chimney as blockages may result.
7. Draft Regulator –Ensure damper is level. See instructions included with regulator.
8. Normal Draft Settings –When properly installed, Triton models are designed to operate with -0.04” w.c.
draft in the flue breaching. For proper operation, there must be enough natural or mechanical draft. Due to
the design of the Triton, it may operate at a positive over fire pressure up to +0.03 at -0.02 draft.
9. Draft Gauge (if applicable) –A barometric control can be used to adjust the draft opening by installing it in
the breeching. This is optional and typically only done when excessive draft conditions exist which must be
relieved or to comply with applicable codes or regulations.
10. Sealing –Seal all vent joints.
11. Blocked Vent Switch –Install switch 6-8” from boiler breeching (Canada). See manufacturer’s instructions.
12. Interlock Set-up –Interlock burner with fan operation before start-up if using a motorized damper to supply
outdoor combustion air or induced draft.

6.0 BOILER PIPING
Boiler Water
Pressure - Triton boilers are intended to solely for use in pressurized closed-loop heating systems operating with
a “fill pressure” between 12-15 psi at the boiler outlet and a Relief Valve pressure of 30 psi (maximum
working pressure of the boiler).
Oxygen Elimination - The Triton boiler is designed to operate in a pressurized closed-loop heating system, free
of air and other impurities. To avoid the presence of oxygen, ensure all of the air is removed from the system
during commissioning via strategically placed, adequately sized air-removal devices located throughout the
heating system and the boiler piping (Figure 6-1). Immediately repair any leaks in the system plumbing to
avoid the addition of make-up water; make-up water provides a source of oxygen and minerals that may lead
to heat exchanger failure, poor performance, unnecessary wear of system components, and premature failure.
The Triton is not approved for operation in an “open system”, thus it cannot be used for
direct potable water heating or process heating of any kind.
Antifreeze - If using antifreeze, use an inhibited propylene glycol specifically designed for hydronic
systems.
Near Boiler Plumbing
Install boiler piping for central heat and domestic hot water as shown in Figure 6-1.
Gauges –The temperature and pressure gauges (Tridicator) is factory supplied and must be field installed in the
front of the boiler or on the coil plate.
Relief Valve –A 30 psi relief valve is factory supplied and must be field installed.
Piping –The closed loop piping system must be in accordance with the central heat piping illustration. All piping
joints must be secure and water tight or the boiler warranty is void.
Water Supply - Pressure regulating “fill valve” (12-15 psi) and back flow preventer are required (Figure 6-1).
Boiler Venting - Hot waters boilers are designed to operate with the airless water in the system. The NY Thermal
boilers are designed with a built-in air trap, to purge air at the ¾” relief valve nipple. An air vent must be
installed here or the boiler warranty is void.
Low Water Cut Off (LWCO) –The HydroStat 3250, when installed in a Triton boiler,
cannot be used as a LWCO due to it’s location in the boiler; therefore, a standard well is
factory supplied with the unit. If a LWCO device is required, an external LWCO must be
field installed to provide protection against firing with low water levels. Failure to follow
these instructions may result in fire, serious injury or death.
Removing Air - Do not fill the boiler with water until you are ready to fire the burner.
Once filled with water, bring the boiler up to temperature and remove the air.
Removing Air from the Boiler:
1. Open automatic air vent 1 turn.
2. Bleed air from system. Starting at the lowest point in the building, open air vents one at a time and leave them
open until water comes out. Close all air vents, except the automatic air vent.
3. Refill to correct pressure, 12-15 psi.

7.0 FIELD WIRING
All wiring and electrical grounding must be in accordance with local codes and the applicable National Electrical
Code, NFPA 70 (USA) or CSA C22.2 (Canada). Ensure that the wiring complies with this manual.
Avoid Shocks - To Avoid Electrical Shock, turn off electrical power to the boiler prior to
opening any electrical box within the unit. Ensure the power remains off while any
wiring connections are being made. Failure to follow these instructions may result in
component failure, serious injury or death.
Wire Protection - When passing any wiring through the casing of any component or
electrical box, the installer must use wire grommets suitable for securing the wiring and
preventing chafing. Failure to follow instructions may result in component failure,
serious injury or death.
Burner Primary Safety - Blocked Vent Switch and any other limit device must break
power to the burner primary (B1). Failure to follow these instructions may result in
serious injury or death.
Labeling - Label all wires prior to disconnecting them when servicing controls. Wiring
errors can cause improper and dangerous operation. Failure to follow instructions may
result in property damage or personal injury.

Fuel Smart HydroStat Model 3250-Plus
The Fuel Smart HydroStat 3250-Plus is manufactured by HydroLevel Company. It is a Temperature Limit and
Reset Control for oil and gas fired boilers. It meets the September 2012 requirements for “Automatic Means”of
adjusting boiler temperature. The HydroStat provides only temperature and reset functionality when installed on a
standard immersion well used on Triton models.
Temperature Limit –In lieu of the HydroStat 3250 the Honeywell Aquastat models L7224A, L7224U or
L8124A can be used on Triton boilers.
Low Water Cut Off (LWCO) - The HydroStat 3250, when installed in a Triton boiler,
cannot be used as a LWCO due to it’s location in the boiler; therefore, a standard
immersion well is factory supplied with the unit. If a LWCO device is required, an
external LWCO must be field installed to provide protection against firing with low
water levels. Failure to follow these instructions may result in fire, serious injury or
death.
Infloor Radiant Heating Applications - When the heating system incorporates low
temperature radiant heating, external mixing controls must be used to regulate the
temperature. Failure to follow these instructions may result in property damage.
Cold Start Will Void Warranty - Upon power up to the control, increase the LO TEMP
setting to a minimum of 120oF. Failure to do so will permit the unit to operate as a cold
start boiler and void the warranty.
HydroStat 3250 - For complete installation details and instructions on controls operation,

LO TEMP:
oMinimum permissible boiler temperature, burner will fire without demand when temperature drops below
the LO TEMP setting.
oController inhibits circulator operation (120V outputs at C1 and ZC are deactivated) until the temperature
exceeds the LO TEMP setting.
o“Tankless Coil” – set LO TEMP to a minimum of 140ºF to obtain DHW priority. Remove jumper (see
HydroStat instructions) to permit LO TEMP settings in excess of 140ºF.
oSet LO TEMP at least 10ºF below HI TEMP setting.
oSee “Setting the Low Limit” in the Hydrolevel installation instructions included with the HydroStat 3250.
ECONOMY
oEstablishes the Boost Interval and Subtractive Differential settings for Thermal Targeting; see Thermal
Targeting Method below.
oEstablishes the Reset Ratio setting for Outdoor Reset operation: see Outdoor Reset Method below
oThe higher the setting the greater the reduction in boiler operating temperature and fuel consumption.
oDHW with a tankless coil, ECONOMY should be set to “OFF”.
oDHW without a tankless coil (Indirect Water Heater), ECONOMY is set in accordance with the
instructions provided under Thermal Targeting or Outdoor Reset Method.
Thermal Pre-Purge
oWhen set to ON, the control will purge the boiler temperature down to 135oF at the start of any thermostat
call before firing the burner. Display indicates "Pur" when control is in Thermal Pre-Purge mode.
oTo set Thermal Pre-Purge ON, perform the following steps:
1. Turn the LO TEMP dial to “Pro”.
2. Turn the HI TEMP dial to select feature 1.
3. Push the Test/Settings Button to turn Thermal Pre-Purge ON or OFF.
4. Reset LO TEMP and HI TEMP settings to desired temperatures.
Zone / Indirect Switch

oSwitch = "Z" (Zone) –ZC-ZR demands are treated as central heat/thermostat demands; Thermal
Targeting and Pre-purge features are active.
oSwitch = “I” (Indirect) – ZC-ZR demands are treated as DHW demands; Thermal Targeting and Pre-
purge features are overridden, boiler operates to the HI TEMP Setting.
oIf ZC-ZR input is not used (i.e. nothing is wired to it), the Zone/Indirect Switch setting is irrelevant.
Outdoor Sensor - The outdoor sensor (p/n: 83604) is included in the burner kit, it must be
connected to the Fuel Smart HydroStat Control 3250 prior to setting up the control.
Warm Weather Shutdown (WWSD)
The Warm Weather Shutdown feature prevents the boiler from providing central heating when the outside
temperature reaches a level that you select. The boiler will still operate to satisfy a call for domestic hot water.
Available settings range from OFF or 40°- 70°F (factory default = 70°F).
To adjust the WWSD setting, press and hold the Test/Setting Button and simultaneously adjust the Economy
dial to the desired setting.
