Safety Issues

Use only the gas type indicated on the
rating plate of the water heater which is
located at the bottom right side panel.

WARNING

Conversion of this appliance from natural gas to
propane CAN ONLY BE PERFORMED by a trained
technician using approved QUIETSIDE parts.

CAUTION

In winter season, the water heater should be kept
connected to an electrical supply, even when the
water heater is not used, to prevent freezing. POWER
SUPPLY IS 115V – 1PH – 60Hz. If the Check Lamp is
“LIT” during the operation, it means that the gas
supply has run out. Check the lamp frequently.
(For other troubleshooting, see page 35 and 38)

CAUTION

Do not use the water heater for other purposes than
heating and hot water use, such as clothes drying,
cooking, etc. Fire may occur.

WARNING

Do not touch the water heater with wet hands. Do
not pour water directly to the water heater for cleaning.
An electric shock may occur.

Use soapy water on the piping and connections to
check for any gas leakage.

Have a professional check the water heater at least
once a year. It will help extend the service life and
ensure safe and efficient operation.

Safety Issues

Hot water temperatures required for automatic dishwasher and laundry use can cause scalds and

burns resulting in serious personal injury and/or death.

The temperature at which injury occurs varies with the person's age and time of exposure.

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.

The water heater 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 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 water heater temperature at 120°F will reduce the risk of scalds. Some states require
settings at specific lower temperatures. The table below shows the approximate time-to-burn
relationship for normal adult skin.

Table- Risk of Scalds

Temperature

Setting

Over 170 ℉ Nearly instantaneous

160 ℉ About 1/2 second
150 ℉ About 1-1/2 second
140 ℉ Less than 5 seconds
130 ℉ About 30 seconds

120 ℉ of less More than 5 minutes

USE ANTI-SCALD VALVE(S) IN HOT WATER SYSTEM TO REDUCE THE RISKS OF SCALDING AT
POINTS OF USE SUCH AS LAVATORIES, SINKS AND BATHING FACILITIES.

Time to Produce 2nd 3rd

Degree Burns on Adult Skin

Scalds – First Aid

1. Remove clothing; Remove all wet clothing, quickly. Wet clothing retains the heat.

2. Apply cold water for 30 minutes; Immediately submerge the burnt area in cold water for 30

minutes to reduce the heat in the skin, preventing deeper burning. Never use butter, oils or ointment
to cover the burn. They may retain the heat.

3. Keep the scalded person warm; Place a blanket around the person.

4. Seek medical advice; Call your medical advice hotline and describe the scald, follow their directions.

Advantages of

QVM 9

Hydronic Heating System

THE QVM 9

QUIETSIDE’S VARIABLE-CAPACITY-MULTI-PURPOSE

90%+ HYDRONIC HEATING SYSTEM

How Does it Work

The QVM 9 provides 2 different heating functions that operate independently from the same water heater. One
mode provides space heating water to heat the home. The other mode provides a continuous circuit of hot
water for domestic use e.g., bath, laundry, etc. Both circuits are separate and operate at different temperature
ranges.

The space-heating water is controlled by the FR-5 thermostat. A special thermostat has been provided that
enables the user to either set the room temperature required or set the heating water temperature. In some
cases this thermostat may not be suitable for multi-system applications(The installing contractor will make this
determination and install suitable alternative controls).

The domestic hot-water is controlled by the user. Because the QVM 9 is a multi-purpose design, it can
provide hot water on demand. There is no storage tank to hold hot water, when there is no use for it. The
QVM 9 will only produce hot water when you use it : instantaneously. The modulating gas burner allows water to
heat up evenly as it is being used. The QVM 9 will continue to heat the water until the source or sources are shut
off. This on-demand-use also helps to prevent water being held in the water heater for long periods of time.

IMPORTANT :

A thermostatic mixing valve should be installed on the domestic water supply pipe to control the supply water

temperature and prevent any possibility of scalding.

7

Domestic Hot Water Priority

The QVM 9 prioritizes domestic hot water over space-heating water and will immediately stop producing
space-heating water the moment a hot water faucet or valve is opened anywhere in the home. Once the faucet
or valve has been turned off, the water heater will return to the home-heating function again.

The Sealed-Combustion Process

The QVM 9 is designed with a special sealed-combustion venting process. Both sides of the combustion
process(inlet oxygen and outlet carbon monoxide) are isolated from each other and are totally sealed-off from
the air supply within the home. Infiltration, is reduced by as much as 90% making the QVM 9 one of the safest,
most comfortable and clean-burning water heater in the world.

industry standards.

■ Piping must be cleaned and

flushed-out before installation.

■ Do not apply torch heat within 12" of the bottom

connections of the unit.

■ Perform all solder connections at a safe distance

from the (brass) male connectors below the unit.
Allow fittings to cool, before attaching to unit. Use
only approved coupling unions with O-rings to
attach field piping to unit.

■ The ‘heating’ pipe should be 3/4" and of type-L

copper, or PEX. Never use aluminum, PVC, or
galvanized steel piping.

■ The pipe size used for

Precautions for Installation

■ Piping for heating and hot
water should be cleaned
before connecting to the unit.

CAUTION

Lime scale accumulation can reduce the life of the
equipment, reduce efficiency and waste fuel. Water heater
failure due to lime or scale buildup voids the warranty.

Check the metal tag on the relief valve and compare it to
the water heater’s rating plate. The pressure rating of the
relief valve must not exceed the working pressure shown on
the rating plate of the water heater. In addition, the hourly
BTU rated temperature discharge capacity of the relief valve
shall not be less than the input rating of the water heater.

NO VALVE IS TO BE PLACED BETWEEN THE RELIEF
VALVE AND TANK. DO NOT PLUG THE RELIEF VALVE.

The drain line connected to this valve must not
contain a reducing coupling or other restriction and
must terminate near a suitable drain to prevent water
damage during valve operation. The drain line shall be
installed in a manner to allow complete drainage of
both the valve and line. DO NOT THREAD, PLUG OR

CAP THE END OF THE DRAIN LINE.

■ The water heater needs a large quantity of air for

combustion, the specified vent must be installed.
If not incomplete combustion will occur and
prevent normal operation of the water heater.

WARNING

For safe operation, an ample supply of air must be
provided for proper combustion and ventilation in
accordance with the national fuel gas code, ANSI
Z223.1 or CAN/CGA-B149.1 or B149.2(latest editions)
or applicable provisions of the local building codes. An
insufficient supply of air may result in a yellow, luminous
burner flame, carboning or sooting of the finned heat
exchanger, or create a risk of asphyxiation. Do not
obstruct the flow of combustion and ventilation air.

NEVER OPERATE THE HEATER UNLESS IT IS
VENTED TO THE OUTDOORS AND HAS ADEQUATE
AIR SUPPLY TO AVOID RISKS OF IMPROPER
OPERATION, FIRE, EXPLOSION OR ASPHYXIATION.

■ The water heater should be
at least 24” away from
electric appliances. The
water heater is set up for
AC 115V 60Hz.

WARNING

The flow of combustion air to the water heater

must not be obstructed.

The water heater area must be kept clear and free
from combustible materials, gasoline and other
flammable vapors and liquids.

■ Flue made of schedule 40

PVC or stainless steel.

■ To facilitate the discharge

of exhaust gas, the flue
should be installed with
fewest possible bents and
curves. The flue should
have a diameter larger than
that of the flue of the water
heater.

■ Do not place flammable

items near the water heater.
Never place combustibles
such as vinyl bags, matches,
thinner, etc on water heater.

CAUTION

Installation

WARNING WARNING

There is a risk in using fuel burning appliances in
rooms or areas where gasoline, other flammable
liquids or engine driven equipment or vehicles are
stored, operated or repaired. Flammable vapors are
heavy and travel along the floor and may be ignited by
the igniter or main burner flames causing fire or
explosion. Some local codes permit operation of gas
appliances if installed 18-inches or more above the
floor. This may reduce the risk if location in such an
area cannot be avoided.

Flammable items, pressurized containers or any
other potential fire hazardous articles must never be
placed on or adjacent to the water heater.

Open containers of flammable material should not be
stored or used in the same room with the water heater.

DO NOT INSTALL THIS WATER HEATER DIRECTLY
ON A CARPETED FLOOR. A FIRE HAZARD MAY
RESULT. Instead the water heater must be placed on

a metal or wood panel extending beyond the full width
and depth by at least 3-inches in any direction. If the
heater is installed in a carpeted alcove or closet, the
entire floor should be covered by the panel.

QVM 9

Series 6

Gas Piping Connections

■ Use metal pipe or metal flexible pipe which has

been approved for use with gas and be sure to
install the shut off valve.

■ If propane gas is in used, the care should be

exercised for the following:

－ Use a household regulator for propane gas with

the capacity matching to the indicated gas
consumption of the unit.

－ Install two or more 110 lbs propane gas

cylinder (manifold cylinders together).

WARNING

This water heater is not intended to operate at gas
supply pressures other than those shown on the rating
plate.

Exposure to higher gas supply pressure may cause
damage to gas valves, which can result in fire or
explosion. If overpressure has occurred, such as through
improper testing of gas lines or emergency malfunction
of the supply system, the gas valves must be checked
for safe operation. Make sure that the outside vents on
the supply regulators and the safety vent valves are
protected against blockage. These are parts of the gas
supply system, not the water heater. Vent blockage may
occur during ice build-up or snow storms.

When local codes require a main manual shut-off
valve outside the water heater jacket, a suitable main
manual shut-off valve must be installed in a location
complying with those codes.

It is important to guard against gas valve fouling
from contaminants in the gas piping. Such fouling
may cause improper operation, fire or explosion. If
copper supply lines are used they must be approved
for gas service.

Before attaching the gas line be sure that all gas
pipe is clean on the inside.

To trap any dirt or foreign material in the gas supply
line, a dirt leg (sometimes called drip leg) must be
incorporated in the piping. The dirt leg must be readily
accessible and not subject to freezing conditions.
Install in accordance with recommendations of gas
supplier. Refer to national fuel gas code, ANSI Z223.1
or CAN/CGA-B149.1 or B149.2 (most recent edition).

■ Gas piping for water heater should be connected to

the main gas line and should not be shared by
other gas appliances.

Series 16

Gas Piping Connections

Standard Gas Piping

Consult with your gas provider to determine the proper diameter of gas pipe. This will
vary due to input capacity, the number of elbows and length of pipe.

■ The heating water supply piping should be 3/4″. An isolation (ball-type) valve should be installed before the
piping is connected to the units.

■ Black iron piping or 3/4″ flexible connector (approved by the local authorities for gas) should be used for gas
piping.

■ Do not use Teflon tape for gas pipe connections.

■

Install a gas drip leg at the unit.

■ Gas piping should be kept at the required distance away from any electric lines and the main service
panel(check with local authorities).

Items Distance (inches)

1. Distance from electric lines 6″

2. Distance from electric heaters and electric panels 24″

3. Distance from flue pipes and outlets 12″

■ Install the ball valve(cut-off valve) before connecting the gas piping to the unit (Allow space for the lever’s full
movement, install valve as close to the unit as possible).

■ After the gas pipe has been completed, all connections must be checked with soapy water. Note! - Do not
test for gas leaks by pumping air-pressure into the line without first disconnecting the gas line to the unit.
Pressuring the unit will void the manufacturers warranty. Releasing this pressure into the unit will cause
immediate and severe damage to the gas valve and its internal pressure regulating device and could result in
property damage and/or personal injury.

About the FR-5 Thermostat

Advantages of the Model FR-5 Thermosta

■ Quietside offers new and improved ways of

getting the best comfort from your new unit.

The FR-5 thermostat is an advanced, multi-

function room thermostat that features a direct­readout L.E.D. panel giving you accurate
temperature control of your environment as well
as displaying information about the performance
and condition of your hydronic heating system.

■ There are two ways of sensing temperature for the

purpose of heating your home ; the most common
is simply by sensing the air temperature within the
main living area, typically where you spend the most
time. The other is by sensing the exact temperature
of the heating water delivered by the unit.

■ With the FR-5 thermostat, both of these methods are

available to you. Now you can choose the simplicity
of setting your temperature by air(maintaining room
temperature) or the convenience and comfort of
setting your temperature by water(maintaining a
constant heating-water temperature).

■ The temperature of the air within the living space

of the home can vary from five to ten degrees. It
is difficult to sense the exact temperatures of all
areas within the home when the thermostat is
located in just one room.

■ Well-insulated homes of average design and

families with active lifestyles should find that
setting the thermostat to the air temperature­sensing function will provide the best comfort.

■ Other homes with unusually high ceilings,

inadequate insulation, leaky windows, long drafty
hallways or simply have people who tend to feel
drafts and chills more than others could find that
setting the thermostat to the water temperature­sensing function will provide the best comfort. We
suggest trying them both.

[The Air Temperature Mode]

The QVM 9 hydronic
heating system has built­in artificial intelligence. In
the air sensing mode, the
FR-5 thermostat is busy
tracking the room set­temperature.

By incorporating the use
of a pre-programmed microchip, the QVM 9 hydronic
heating system accurately adjusts the modulating combustion
process to best suit the changing needs of the home.

Water Temp.

Average(℉)

[The Water Temperature Mode]

In the water-sensing mode,
the FR-5 thermostat works
with the unit to maintain a
constant water temperature
condition. There is no sensing
of room temperature in the
water temperature sensing mode
of operating and therefore,
small adjustments and fine

-tuning will need to be made from time to time.

[Energy Saving Mode]

In winter, if you’re leaving
for work or plan to be away
for several hours or several
days, you can select the
‘unoccupied(Away from Home
Saving)’ mode to reduce
energy costs. During these
periods when the home is
vacant, you can program the
thermostat to operate the
unit in a ‘stand-by’ mode where the unit will cease to
operate in the normal heating function. In stand-by, the
thermostat tells the unit to only operate for very brief
intervals; for the period you have selected(anywhere from
0 to 4 hours). When you return. Select the preferred
temperature and press the heating mode button.

On the following pages you will find the FR-5
operating instructions describing how to operate this
device add convenience to your life while keeping
you and your home more comfortable.

QVM 9

Series 22

Installation of the Thermostat

Choosing the Best Location

■ Never locate the thermostat near or above a heat producing source(lamp, TV, fireplace, radiator, direct
sunlight, etc.).

■ Never locate in areas with drafts(stairwells, vestibules, foyers, against an outside/exterior wall, etc.).

■ Never locate in a room, which will be shut-off from the other living areas of the home.

■ On multi-story homes, locate thermostat on the ground floor.

■ Install at a height of about 4 to 5 ft above the floor.

■ Keep out of reach from children.

Installation

1. Remove the back plate from the FR-5 thermostat by grasping the faceplate with one hand and sliding the
back plate downward with the other hand.

2. Pull the thermostat wire through the back plate.

3. Connect 2(orange colored/stranded) wires from unit to the 2 screws located on the FR-5 thermostat.

4. Mount the back plate to the wall using either of the above techniques(depending on the construction of the wall).
Recheck all connections both inside the unit and at the thermostat. Be careful not to pinch the control wires. Pinched
or shorted wires will prevent the system from operating. Do not over tighten wire nuts connecting wires together.
Use countersunk type screws to fix back plate to the wall.

Carefully tighten the 2 screws when connecting the wires. Do not apply excessive force. If the insulation of the wires is
damaged or if the terminals are in poor contact, the room thermostat will not work properly. Be careful to protect the
insulation of the wires.

clearances to walls, ceilings, overhangs, etc.
have been met.

2) Freeze Prevention Device

The units must be wired-in to a 115 volt
electrical circuit once they have been connected
to water piping and the circuit has been filled with
water. If the freeze prevention circuit starts due to
a low-water condition, the pump will begin running
on “air” and cause premature failure and will void
the warranty on the pump.

Check to see if the unit is properly connected
and the piping is insulated properly.

If the insulation has worn off or is not fitted, the
risk of freezing of piping and severe damage to
the unit is considerable. Thoroughly check the
piping insulation and replace where necessary.

exchanger from restricted flow rate and/or blockage (16-20 mesh minimum, 20-40
mesh best choice).

■

CONNECTIONS : Remove 2 philips head screws holding the pipe flange to the plate heat exchanger

while removing the other end of the heating pipe from its anchor point as well. (some
of these fittings may use ‘speed clip’ which slide in and out to release the pipe end.)
Grasp pipe and flange and pull away from the plate heat exchanger being careful not
to cause stress to other fittings and connections. Check O-ring on tube ends and
replace if necessary.

■

CLEANING : In some applications the flat plate heat exchanger may be subjected to severe

conditions, including high temperature and/or hard water conditions, causing
accelerated scaling and corrosion rates, which will impede the performance of the
heat exchanger decreasing the delivery of hot water to the home. Because these
factors it is important to establish regular cleaning schedules. The chemical cleaning
process is very simple for cleaning the Quietside Flat Plate Heat Exchanger, which will
extend the life and performance of the heat exchanger.

A 5% solution of Phosphoric Acid or Qxalic Acid may be used. Other type cleaning
solution can be obtain from you local wholesaler. Do not heat acid solution when
back-flushing through heat exchanger. Flush heat exchanger with plenty of fresh
water after cleaning.

Make sure cleaning solution is applicable for stainless steel and copper that directions
are follow as recommended.

Dimensional Drawing of the Unit

(unit : inch)

■ Safety Valve : When excessive pressure occurs, the valve opens to reduce pressure by draining water.
When leaving home for a long time, water in the water heater should be drained to prevent
freezing of the water heater.

■ Strainer : Increases heating performance by filtering impurities from the system. When heating
performance is decreased, clean the filter by removing clip, washing out and re-inserting
the filter. Replace the clip!

※ Dimensions in “( )” apply 150W1-NG models.

CAUTION

THE WATER FLOWING OUT OF THE PRESSURE / RELIEF VALVE DURING IT’S OPERATION
MAY BE EXTREMELY HOT. BEFORE OPERATING RELIEF VALVE, MAKE SURE DRAIN LINE IS
INSTALLED TO DIRECT DISCHARGE TO A SAFE LOCATION SUCH AS AN OPEN DRAIN. AVOID
SCALDING AND/OR WATER DAMAGE.
