The temperature at which injury occurs varies with the person's age and time of exposure.
Water temperature over 125°F/52°C can cause severe burns instantly or death from scalding.
The slower response time of disabled persons increases the hazards to them. Never allow small children
to use a hot water tap, or to draw their own bath water. Never leave a child or disabled person unattended in a bathtub or shower.
Installation & Operating Instructions
DANGER
The appliance should be located in an area where the general public does not have access to the
temperature control.
Lower water temperatures should be used to avoid the risk of scalding. It is further recommended, in all
cases, that the domestic water temperature be set for the lowest temperature which satisfies the user’s
hot water needs. This will also provide the most energy efficient operation of the water heater and
minimize scale formation in the heat exchanger, thus prolonging the life of the unit.
Setting the domestic hot water temperature at 120°F
jurisdictions require settings at specific lower temperatures. The table below shows the approximate
time-to-burn relationship for normal adult skin.
Hot water temperatures required for automatic dishwasher and laundry use can cause scalds and burns
resulting in serious personal injury and/or death.

PRESSURE DROP (PSI)
2.3.1 Head Calculation
Example: C95 Target ow of 5 gpm
Figure 2.3 indicates 25.5 ft head available at the desired ow of 5 gpm. Figure 2.4 indicates the
pressure drop in the heat exchanger to be 4.4 psi (10.2 ft) at the target ow of 5 gpm.
Therefore 25.5 - 10.2 = 15.3 ft available for piping and heating device pressure drop.
The C140 unit is supplied with a factory low loss header for eld installation. Therefore external head
is provided by the eld supplied secondary loop circulating (CH) pump.

DANGER
The ue exhaust and
combustion air intake are to be
piped separately. The Glow
Combi Boiler cannot share a
common ue exhaust or
combustion air intake with
multiple appliances. Failure to
comply may result in property
damage, serious injury, or
death.
DANGER
Do not install the Glow Combi
Boiler into a common venting
system with any other
appliances. Failure to comply
with this warning may cause
ue gas spillage and leech
carbon monoxide emissions
into the surrounding air
resulting in serious injury or
death.
4. Venting
4.1 General Venting
The Glow Combi Boiler is certied as a “Category IV” boiler requiring a “Special
Venting System” designed for pressurized venting. The exhaust vent must be piped
to the outdoors, using the vent materials and rules outlined in this section. Under
no conditions may this unit vent gases directly into a masonry chimney, unless it
is vacant, and utilizes the approved venting material and rules described in this
section. Venting into a masonry chimney is only acceptable when the chimney is
no longer being used for its initial intended purpose therefore considering it a chase
for the exhaust and combustion air vent pipe.
4.2 Removing an Existing Boiler from Common Venting System
Upon removal of an existing boiler, the following steps shall be followed for
each boiler remaining in the common venting system; prior to commencing this
procedure, shutdown all boilers remaining in the common venting system.
Steps to Removing an Existing Boiler:
When an existing boiler is removed from a common venting system, the common
venting system is likely to be too large for proper venting of the remaining boilers
connected to it. Instructions have been provided on how to remove the existing
boiler and how to resize the remaining venting system. Failure to follow these
instructions may result in property damage, serious injury or death.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch and
determine there is no blockage or restriction, leakage, corrosion and other
deciencies which could cause an unsafe condition.
3. 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 operate at maximum speed. Do not operate a summer
exhaust fan. Close replace dampers.
4. Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust thermostat so appliance will operate continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of main
burner operation. Use the ame of a match or candle, or smoke from a
cigarette, cigar or pipe.
6. After it has been determined that each boiler remaining connected to the
common venting system properly vents when tested as outlined above, return
doors, windows, exhaust fans, replace dampers and any other gas burning
boiler to their previous condition of use.
7. Any improper operation of the common venting system should be corrected
so the installation conforms to the National Fuel Gas Code, ANSI Z223.1/
NFPA 54 and/or Natural Gas and Propane Installation Code, CAN/CSA
B149.1. When resizing any portion of the common venting system, the
common venting system should be resized to approach the minimum size
as determined using the appropriate tables in Chapter 13 of the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or Natural Gas and Propane
Installation Code, CAN/CSA B149.1.

ventilation, and dilution air
WARNING
Make up air requirements for
the operation of exhaust fans,
kitchen ventilation systems,
clothes dryers, and replaces
shall 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
personal injury or death
Venting
4.3 Installation Using Indoor Combustion Air
When the installation uses Indoor Combustion Air (i.e. piping is not directly
connecting the appliance air-inlet tting to the outdoors), provisions for
combustion and ventilation air, in accordance with section “Air for Combustion
and Ventilation,” of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 (U.S.),
or Clause 8.2, 8.3 or 8.4 of Natural Gas and Propane Installation Code, CAN/
CSA B149.1 (Canada), or applicable provisions of the local building codes, must
be adhered to.
4.3.1 Contaminated Make-Up Air Will Damage the Unit
Do not to operate the combi boiler in an area that is or will be under construction
or renovation. Combustion air containing dust, debris or air-borne contaminants
will drastically increase the required maintenance and may cause a corrosive
reaction in the Heat Exchanger which could result in premature failure, re, serious
injury, or death. The Glow Brand Manufacturing Warranty will not cover damage
and premature wear caused to the unit due to installation in a contaminated
environment.
All of the exhaust venting connections must be leak checked with a soap solution
upon initial startup of the combi boiler. Any leaks must be repaired before
continuing operation of the unit. Warranty will not be available if the unit is used
for construction heat.
NOTICE
It is BEST PRACTICE to pipe
the combustion air-inlet
directly to the outdoors
(Direct Vent installation) to
avoid contamination often
contained in indoor air.
WARNING
Do not store or use gasoline or
other ammable vapors and
liquids in the vicinity of this or
any other appliance. Failure to
follow instructions may result
in serious injury or death.

4.5 Direct Vent Installation
Direct Vent installation dictates that the combustion air-inlet must be piped directly
to the outdoors using the methods described in this section and in accordance
with the National Fuel Gas Code, ANSI Z223.1 (U.S.) or CSA B149.1 (Canada)
and local requirements. Install the entire venting system securely cementing all
ttings. This Glow Combi Boiler uses a 2” or 3” diameter exhaust vent pipe made
up of PVC or CPVC System 636. The air intake pipe uses 2” or 3” diameter pipe
made of Schedule 40 ABS, DWV, PVC, or CPVC materials and in accordance
with all applicable local building codes.
4.5.1 Exhaust Vent Pipe Materials
Use only 2” or 3” solid PVC/CPVC schedule 40 PVC/CPVC or ULC S636 pipe
and ttings. Venting requirements in USA and Canada are different. Consult the
most recent edition of the National Fuel Gas Code (ANSI Z223.1 / NFPA 54) or
CAN/CSA B-149.1 as well as local codes for applicable venting regulations and
restrictions.
For installation in Canada, eld supplied plastic vent piping must comply with
CAN/CSA B-149.1 (latest edition) and be certied to the standard for type BH
Gas Venting Systems. ULC S636 components of this listed system shall not
be interchanged with other vent systems or unlisted pipe/ttings. All plastic
components and specied primers and glues of the certied vent system must be
from a single manufacturer and not intermixed with other system manufacturer’s
vent system parts. The supplied vent adapters are certied as part of the
combination boiler.
Units installed with vertical exhaust, must have an additional condensate drain
installed on the exhaust vent pipe. Fittings must be ULC S636 approved. Schedule
40 PVC/CPVC pipe/ttings have been approved for use on this appliance with
zero clearance to combustibles.
WARNING
Flammable Cements and
Primers – It is the installers’
responsibility to familiarize
themselves with the hazards
associated with explosive
solvents and to take all
precautions to reduce these
risks. Failure to follow these
instructions can cause
explosions, property damage,
injury or death.
All venting must be supported
to reduce strain on piping
joints. The exhaust vent shall
maintain a 1/4” slope upwards
towards the vent termination
outlet. In situations when
excessive amounts of
condensate is being produced
maintaining a 1/2” slope
upwards towards the vent
termination may be required.
4.5.2 Intake Vent Pipe Materials
Schedule 40 PVC, CPVC or ULC S636 pipe and ttings and ABS or DWV pipe
and ttings can be used for combustion air intake on Glow Brand products.
Transition cement must be used if ABS or DWV pipe is connected to the PVC
appliance adapters.
All plastic components and specied primers and glues of the certied vent
system must be from a single manufacturer and not intermixed with other system
manufacturers vent system parts.
The vent for this appliance shall not terminate over public walkways, near soft
vents, crawl spaces or other areas where condensate or vapour could create a
nuisance or hazard or cause property damage or where condensate vapour could
cause damage or could be detrimental to the operation of regulators, relief valves
of other equipment.
4.5.3 Flammable Solvents and Plastic Piping
Due to the extremely ammable characteristics of most glues, cements, solvents
and primers used in the process of joining plastic vent and air-inlet pipe, explosive
solvent vapors must be evacuated from the vent and air-intake prior to start-up.
Avoid using excess cement or primer that may lead to pooling inside the pipe
assembly. Freshly assembled piping assembly should be allowed to cure before
operating the gas red appliance.

4.5.5 Termination Options
The venting system of the Glow Combi Boiler may be terminated using eld
supplied piping to construct a “Two-Pipe” termination, alternatively, the venting
may be terminated using a manufacturer approved concentric vent kit.
Sidewall Termination
Due to potential moisture building up along the exterior wall, sidewall venting may
not be the preferred venting option. Refer to roof top venting options.
Straight Out Termination – The exhaust vent can terminate straight to an outside
wall. A reducer of 1 pipe diameter smaller can be tted on the exhaust to increase
the velocities of the exiting gases. The reduced diameter pressurizes the exhaust
vent and helps to keep the ue gases from entering the intake. The reduced pipe
diameter of 1 size shall be between 4” to 8” in length.
In the United States (U.S.), provide a minimum of 4 feet (1.22 m) horizontal
clearance from electrical meters, gas meters, gas regulators, and relief equipment
as per National Fuel Gas Code, ANSI Z223.1/NFPA 54. In no case shall the
exit terminal be above or below the aforementioned equipment unless the 4 foot
horizontal distance is maintained.

4.5.6 Venting Rules and Guidelines
1. Prevailing Winds: Ensure the vent is located where it will not be exposed to
normal prevailing winds.
2. Combustion Air Intake Contamination: Air for combustion must be drawn
from an area free of dust and contaminants. Combustion air containing
chemicals such as chloride, uoride, bromine, iodine or dust and debris will
cause damage of the heat exchanger voiding your Glow Brand Warranty.
3. Vertical Separation: The exhaust outlet must be a minimum of 8” to a
maximum of 24” above the combustion air intake. The combustion air intake
must always be a minimum of 12” plus snow allowance above any surface
that will support snow.
4. Horizontal Separation: The horizontal distance between the intake and
exhaust must be a minimum of 6” center to center.
5. Flue Gas Hazard: The vent for this appliance shall not terminate over public
walkways, near soft vents, crawl spaces or other areas where condensate
or vapour could create a nuisance or hazard or cause property damage.
Condensate vapour could cause damage or could be detrimental to the
operation of regulators, relief valves of other equipment.

Glow Brand C95 & C140
Venting
6. Vent Sloping: All exhaust piping must maintain a ¼” per foot upwards
slope towards the outlet of the vent termination. For applications where,
excessive condensation is possible, a ½” per linear foot upward slope is
recommended.
7. Vent Supports: All exhaust and air intake piping shall be secured to the wall
for rigidity. Exhaust and air intake pipe must be supported horizontally and
vertically at a maximum of every 4 feet.
8. Roof Exhaust: In all roof applications the discharge must point away from
the pitch of the roof and must be a minimum 24” apart.
9. Roof Flashing: Install adequate ashing where the pipe enters the roof, to
prevent water leakage.
10. Venting Below Grade: For installations that exit the wall below grade, refer
to the latest version of the CAN/CSA B149.1 Natural Gas and Propane
Installation Code.
11. Vent Screens: Factory supplied vent screens may be installed on the intake
and or exhaust termination. Two ½” by ½” galvanized screens are provided
in a package. Vent screen installation is optional.
12. Condensate Hazard: Do not locate vent over public walkways, driveways
or parking lots. Condensate could drip and freeze resulting in a slip hazard
or damage to vehicles and machinery.
13. Venting Options: Due to potential moisture loading (build-up) along the
exterior wall, sidewall venting may not be the preferred venting option.
