Safety Information
Read and understand this Instruction Manual
thoroughly before installing and using this
boiler.
Any appliance that burns natural gas, propane
gas, fuel oil, wood or coal is capable of
producing carbon monoxide (CO). CO is a gas,
which is odorless, colorless and tasteless but is
very toxic.
If your HearthStone Hydronics boiler is not
working properly, or is not vented properly,
dangerous levels of CO may accumulate. CO is
lighter than air and thus may travel throughout
the building.
•WARNING: Brief exposure to high
concentrations of CO, or prolonged
exposure to lesser amounts of CO may
result in carbon monoxide poisoning.
Exposure can be fatal and exposure to
high concentrations may result in sudden
onset of symptoms including
unconsciousness.
The symptoms of CO poisoning are often
confused with those of influenza, and the
highest incidence of poisoning occurs at the
onset of cold weather or during flu season. A
victim may not experience any symptoms, only
one symptom, or a few symptoms. Suspect the
presence of carbon monoxide if symptoms tend
to disappear when you leave your home.
The following signs may indicate the presence
of carbon monoxide:
•Hot gases from appliance, venting system,
pipes or chimney, escaping into the living
space.
•Flames coming out around the appliance.
•Yellow colored flames in the appliance.
•Stale or smelly air.
•The presence of soot or carbon in or around
the appliance.
•Very high, unexplained humidity inside the
building.
If any symptoms of CO poisoning occur, or if
any of the signs of carbon monoxide are present,
vacate the premises immediately and contact
a qualified heating service company or the
gas company or the fire department.
To reduce the risk of CO poisoning, have your
heating system “tuned up” by a licensed heating
contractor or the gas company –preferably
before each heating season. Also, have the
service company check your chimney or vent
Symptoms of CO poisoning include the
following: Dizziness, Vision problems,
Shortness of breath, Headache, Nausea, Loss
of muscle control, Unclear thinking,
Weakness, Unconsciousness.

Setting Up Your
H-Series Boiler
Boiler Location
Locate the boiler to provide sufficient clearance
for inspection, servicing and maintenance.
Minimum clearance to construction or
combustible materials should not be less than
six (6) inches from the top, sides, and rear of
unit, and eighteen (18) inches from the flue pipe
in any direction. Front clearance should be at
least twenty four (24) inches. Greater distances
for ease of access should supersede fire
protection clearances. The boiler must be
located on a non-combustible floor. A Smooth,
level concrete floor is recommended. If the
boiler is to be installed on combustible flooring,
consult local authorities for proper method of
covering floor. This boiler must not be installed
on carpeting.
Piping
All piping must conform to state and local
codes.
Be sure to provide unions and gate valves at the
inlet and outlet of the boiler, so it may be
readily isolated for service. Install the pressure
relief valve so the discharge is piped directly to
the drain, if possible. If not, the discharge
should be piped to the floor. In either case the
discharge pipe should be the same diameter as
the outlet of the relief valve, with no valves or
obstructions to impede overflow from the boiler.
It is recommended that the make-up water line
have a backflow preventor installed adjacent to
the boiler.
NOTE: If the heating system is to be filled with
antifreeze, use only formulations expressly
made for hydronic heating systems (such as
propylene glycol). Do not use automotive
types of antifreeze (ethylene glycol). Use of
antifreeze will alter system output and
characteristics.

If the block needs to be split into sections for
ease of delivery, please read the following:
To assemble split blocks, move sections into
parallel and facing each other. Sections may be
slid along boards placed underneath the
sections. Inspect nipple ports for damage or
burrs. Remove any burrs by scraping the port
very lightly.
Wipe the push nipples and nipple ports with a
clean cloth. Apply a film of nipple compound to
both the nipple and the port. Install the nipple in
the port and then seal by hitting with a hammer
cushioned with a block of wood.
Apply section sealant to one section only and
slide sections together. Install the four draw
rods and draw the sections together evenly
(measure with a yard stick). Draw sections
together until section together until sections
make iron-to-iron contact at a point around the
top and bottom ports of each section. Do not
over-tighten draw rods.
After assembly of boiler blocks, seal all joints
with furnace cement and remove boards.
NOTE: When cutting off excess length of draw
rods, allow enough length to install boiler
jacket, which mounts on the draw rods.

Combustion Air
Supply
The H-Series Boiler must be installed in a
location where available ventilation provides
sufficient air for combustion, proper venting of
combustion gases, and maintenance of safe
ambient air temperatures at safe limits under
normal conditions.
If your home is well insulated or especially well
sealed, the infiltration air supply to the interior
of the house may be inadequate. If normal
infiltration is not sufficient, outside air is
required: Under these conditions, a permanent
opening or openings having a total free area of
not less than 1 square inch per 4000 Btu/hr (35
in.2per gal/hr), based on the total input rating
of all appliances in the space, must be provided.
Figure 8: Ventilated Spaces
NOTE: If the boiler is installed in a building
where operation of exhaust fans, attic fans,
kitchen ventilators, clothes dryers or fireplaces
may create negative venting pressures, causing
unsatisfactory combustion or venting, special
provisions must be made for additional make up
air for those other appliances.
If air filtration to the building is sufficient, and
other appliances are not a problem, inside air
will be provided: A boiler room typically has
two permanent openings to inside the building,
one near the top of the space and one near the
bottom. Each opening must have a free area of
not less than 1 square inch per 1000 Btu/hr (140
in.2per gal/hr), based on the total input rating
of all appliances in the space. Each opening
must freely communicate with interior areas of
the building that, in turn, have adequate
infiltration from outside.
In calculating the free area required, the
blocking effect of louvers, grilles, or screens
protecting openings must be taken into
consideration.
Screens used in louvers or grilles must not be
smaller than ¼” (63mm) mesh and must be
accessible for cleaning.
If the free area of the design of a louver or grille
is not known, it shall be assumed that wood
louvers will have 20-25 percent free area and
metal louvers and grilles will have 60-75
percent free area.
WARNING: Do not connect the boiler to any
air distribution duct or system.
A Direct Vent kit is available from your
dealer for through the wall venting. A Direct
Vent Kit provides for thru-the-wall venting
with makeup air provided. For more
information, contact your local HearthStone
Hydronics dealer.
Boiler

Quality Home Heating Products Inc®H-Series Boiler 11
Venting System and Breaching
The H-Series Boiler must be vented to the
outdoors by means of a tile lined masonry
chimney or an approved prefabricated chimney
of the size and height recommended by the
manufacturer.
The H-Series Boiler must be connected to an
approved, listed venting to remove combustion
(flue) gases. Maintain NFPA 211 clearances at
all times.
We recommend a 6” round, insulated, chimney
liner or equivalent. Oversized chimneys may
cause condensation and eventual chimney
failure. Exterior masonry chimney may need to
be lined to prevent condensation, and eventual
failure.
Secure all joints, including attaching the
chimney connector to the boiler’s flue collar,
with three sheet metal screws. Install #10 x½”
(3 mm x 13 mm) sheet metal screws into the
holes pre-drilled in the flue collar. You can
simplify connecting stovepipe by using
additional accessories such as telescoping pipes,
slip-connectors, and clean-out tees.
Install the boiler as close as practical to the
chimney, while maintaining all proper
clearances. Install stovepipe that is as short and
as straight as possible. Horizontal runs of
stovepipe should always rise away from the
boiler a minimum of ¼” per foot of horizontal
runs.
Some installations may require a Barometric
damper, such as atall chimney which can
create a higher than normal draft. In such cases,
a barometric damper can help regulate the draft.
A manually operated damper cannot be placed
in the chimney connector from an oil-burning
appliance.
Where two or more oil-burning appliances are
connected to a common chimney, a manual
isolating damper may be permitted.
If installed, they will be interlocked to prevent
the burner from operation unless the damper is
in the full open position.
Automatically operated dampers must be of an
approved type, must be designed to maintain a
safe damper opening at all times, and must be
arranged to prevent starting of the burner unless
the damper is fully opened.
Venting Terminations
The termination of venting systems must be
located 24 inches above any part of the building
structure within 10 feet of the chimney (Refer to
figures 9 +10). Be sure that the venting system
does not become obstructed with squirrel
activity, bird nests, soot buildup, chimney liner
deterioration, etc.

Burner Setup
Burner Kit: To be installed after the Trim kit is
complete.
The burner assembly that is used may be only
one approved for use with this boiler. Models of
Carlin, Beckett, and Riello burners have been
approved for use with the HearthStone H-series
Boiler. These are the recommended burners for
use. The components for each burner will vary
depending on which manufacturer is being used
in this installation.
The H-Series boilers are shipped as factory
assembled and sealed blocks, from three (3) to
nine (9) sections in length.

Quality Home Heating Products Inc®H-Series Boiler 13
The H-series Boiler is so versatile; it can be
easily adapted for use with any of three burner
systems. Beckett, Riello, or Carlin. The
mounting procedure for each of the three is the
same. (Please refer to figure 6 for proper
placement of the burner.)
•Place the four 8mm x 31mm burner
retention studs, that were shipped in the
trim kit box, into the front castings
threaded holes. (the shorter section of
threads will go into the cast)
•Slide the burner system over the studs.
Align the slotted pattern over the
threaded studs. (Careful not to damage
the exposed threads)
•Slide the four flat washers over the
studs. Using the four nuts provided,
fasten them, securing the placement of
the burner assembly.
The setup of the burner from this point
forward depends upon which burner has
been equipped with this unit. Some of the
following information may not relate to your
burner. Determine which burner this boiler
is equipped with and locate the section that
applies to that burner. Each burner will have
it’s own set of installation instructions.

Controls and Features Before operating
your Boiler, become familiar with the location
of the Safety Features and any user controls
installed. Ask your installing contractor where
the shut off switch is located. For your own
safety, do not modify or re-set any controls
yourself in any way
Due to the variance in operating instructions
from burner to burner, we will not list the
procedure for each in this manual. Each burner
assembly contains a full set of operating
instructions and trouble shooting guides. Refer
to the addresses and support phone numbers on
pages 14 + 15 for the burner manufacturers
Cleaning and Maintaining Your
Boiler
Check for fouling or soot buildup in the
combustion chamber at least every twelve (12)
months.
¦CAUTION: Black carbon soot in the
combustion chamber can, under certain
conditions, be ignited by a spark or open
flame. To prevent this unlikely occurrence,
damped soot deposits with a wet brush or a
fine water spray before servicing or cleaning
the combustion chamber.
Fouling or carbon soot buildup on the surfaces
in the combustion chamber is caused by
incomplete combustion, and is a sign of
combustion air and/or venting problems. As
soon as any fouling is observed, the cause of the
fouling should be corrected and the combustion
chambers should be cleaned as follows:
1. Disconnect the electrical power supply to
the boiler, burner and controls.
2. Open the swing door.
3. Brush and vacuum the combustion
chamber and flue passages until all
deposits are removed.
