DESCRIPTION AND FEATURES

The Girard Products GSWH-1 LP Gas Tankless Water Heater is designed to meet ANSI

Z21.10.3-

2004 and CSA

4.3-2004

and is certified by the Canadian Standards Association (CSA)

to meet

these standards for use in recreation vehicles.
The design of this product differs from the traditional storage tank water heater units found in

RVs. More

specifically:

•

The Girard Tankless Hot Water System

uses a

finned copper heat exchanger and nine

high

efficiency blade burners

•

The Motor Aided Induced Draft enhances combustion for increased efficiency and

improved

wind resistance

•

A Dual BTU Gas Valve optimizes the output temperature range based on the temperature of

the input cold water and water flow

When properly installed in a Recreation Vehicle the Girard Tankless Water Heater is connected

to:

•

The

RV’s cold water system with its water input from a pressurized (45 psi) source such

as

a shore connection or a water storage tank with

water pump.

•

The

RV’s hot water system (i.e. faucets and

shower)

•

The

RV’s LP Gas system capable of supplying the rated

BTU

requirement.

•

The

RV’s 12VDC Electrical power distribution panel on

a 10

amp fused circuit

Please refer to the Owners Manual supplied with the unit for further information. The Owners
Manual will allow you to verify if the unit is properly installed and the connections are within the
following recommended parameters:

•

The pressure of the water supply is between

40

and

60

psi for normal

opera

tion

•

The LP Gas system is operating within the inlet pressure limits indicated on the rating

label

(10.5” and 14” WC)

•

The DC Voltage

applied is greater than

11.5

and less that

14

VDC

NORMAL OPERATION

A tankless water heater, also referred to as an “on demand” water heater, rapidly heats water as
it flows around and through the heat exchanger. The

output water temperature depends on the
temperature of the input water and the flow established at the faucet by the user; the faster the
flow, the cooler the water; the slower the flow, the hotter the water.

The gas control valve of the GSWH-1 and the GSWHAF-1 features a dual BTU

solenoid that can

operate

in ‘High’

mode (34,000

BTUs) or ‘Low’

mode (27,000

BTUs)

depending on the

input

temperature of the cold water. Colder water (65°F or less) causes the burner to operate in

‘High’. Warmer water (70°F or more) causes the burner to operate

in ‘Low’. NOTE: When

the

input water temperature is between 65°-70°F the unit may operate

in ‘High’ or ‘Low’

depending

upon precise thermostat settings. A thermostat setting may vary

+/- 5°F.

Prior to normal operation the user must ensure that all air has been purged from the water lines,

the Water Heater Power Switch is in the ‘ON’ position and the REMOTE

Mode Switch (see below)

is set in the desired position (AUTO or LO). The 12VDC power is normally left ON while the RV

is

in

use

with no

use

of LP

gas.

In many

cases

the switch may

be set

to ‘On’ the entire

camping

season. This will not harm the unit in any way.
To start the water heater the user should fully open the hot water faucet, wait for hot water

to flow

and decrease the flow (which results in hotter water) to obtain the temperature desired.

Note:

although the Girard tankless water heater is instantaneous, the water in the system (pipes)

must

be purged before the user will feel hot water at the faucet. Thus, the further the water

heater is

located from the faucet/shower the longer

it will take for the user to feel hot water.

The

ideal

location for any water heater is in the center of the coach.
During normal operation the hot water faucet behaves somewhat like a typical mixing valve:

it
(faucet) increases the water temperature when turned clockwise (reducing the water flow) and
decreases the water temperature when turned counterclockwise (opening and

increasing the

water flow).
The user may mix the hot water with cold water, but normally this is not recommended: The

increased total flow (Hot plus Cold) will reduce the inlet pressure; which in turn,

reduces the flow
of water through the heat exchanger of the water heater: this will cause the hot water output
temperature to increase defeating the effect of the cold water. In some cases adding cold

water

may result in limiting. (See

last paragraph, this section)

When the Mode switch is set to AUTO, a

thermostat will cause the burner to switch automaticall

y

from High to Low when the inlet water temperature goes above 70 ºF and from Low to High

when it goes below

65

ºF. Note: A

thermostat setting may vary

+/- 5°F.

If the output temperature exceeds 123

ºF an Emergency Cut-Off (ECO)

thermostat will shut

down the unit to prevent scalding; this operation is both normal and desirable and is commonl

y

referred to as

“limiting”.

P a g e

6

As a convenience, a Mode switch is installed to manually force the burner to operate only

in

LOW mode. Operating the system exclusively in LOW

mode allows better temperature control
when inlet water flow is minimal and the inlet water temperature is between 70° and 65 ºF and
the automatic control has not yet automatically switched to Low mode. The switch must

manu

-

ally be reset to Auto in order for the system to operate

automatically.

Important: When the inlet water is below 50 ºF (input water is very cold), the hot water

flow

must be reduced to .75gpm or less .to reach an output temperature above 100 ºF.
If the input water temperature is approximately 60ºF or greater, the model GSWH-1 will genera

te

output water in the range of 95 °F to 120 °F depending on the water flow.

CIRCUIT BOARD OPERATION

When the user opens a Hot Water faucet, water starts flowing through the unit

and activates the

Flow Switch which in turn activates the Relay; this applies 12VDC power to the ECO

(Emergency

Cut-Off Thermostat) and to the “Heat Demand” Connection (5) of the Circuit Board (see below).

Change to: ….ECO (Emergency Cut-Off Thermostat) and to the

‘TH’

Connection (2) of the Circuit

Board.
Power is then applied to the Sail Switch that is open when there is no air flow from the

blower

.

The ECO

is normally closed. The Circuit Board starts the blower and verifies that the Sail Switch

closes: when this occurs the Circuit Board will sense the 12VDC at the Circuit Board

indicating

that there is sufficient air flow for combustion. The circuit is now complete.

Try For Ignition (TFI)

The Circuit Board is now ready to try for ignition and applies power to the gas valve

through
connection (4) and without delay generates a spark of five (5) seconds duration at the igniter. If
the Circuit Board does not sense flame at the spark igniter, the gas valve is de-energized and
an internal post purge of 15 seconds will occur before a second try is attempted. Two additional
tries will be attempted and if no flame is detected in the process the Circuit Board goes into
LOCKOUT mode and will make no further attempt to light. Once

the system has entered lockout

mode, it must be reset. To reset the water heater, turn OFF power to the water heater OR

close

the faucet (removing the demand for hot water for a period of five (5) seconds.

Figure

6

P a g e

11

Whenever the Circuit Board senses flame during the ignition trials, sparking stops and the Gas
Valve remains energized. The Water Flow Switch, the Sail Switch and the Burner flame are
constantly monitored to assure that the system continues to operate

properly.

When the Hot Water faucet is closed and the Flow Switch opens, the demand for heat ends and

the Gas Valve is de-energized immediately; after the post purge and cool off period of

90

+/-

seconds the blower is turned off.

Flame Failure

If the established flame signal is lost while the burner is operating, the control will sense this
and respond within 0.8 seconds. The gas valve will stay energized and the Ignition Spark

will

be energized in an attempt to relight the burner (trial for ignition). If the burner does not

light,

the control will make two more attempts to relight and then go into lockout (See Try

for Ignition­page 10). If flame is

esta

blished.

Combustion Airflow Problems

If the airflow signal is lost, or the ECO opens during heat mode, the gas valve is

immediatel

y
de-energized and the blower stays on. If the switch closes again, a normal ignition sequence
will resume. If not and this condition persists for more than five minutes, the control will enter
lockout (See Try for Ignition - page 10) with the blower off.

ROUTINE MAINTENANCE

We recommend that the GSWH-1 water heater be inspected regularly by the user and at least
once a year by a qualified service technician.
Before an inspection make sure that the LP Gas

and Water supply are connected and turned on.

A routine inspection must include the following

items:

1.

Inspect the integrity of the sealing (caulking or tape) between the side wall and the door
of the water heater and make sure that the unit is solidly mounted to the vehicle.

2.

Verify that the air inlet openings (louvers) are completely open and clear of any

debris

including mud, leaves, twigs, insects etc. Remove all obstructions to allow full air

flow.

3.

Inspect the Exhaust tube and make sure that it is also unobstructed and that the Exhaust
screen is clean.

4.

Open

the cover and verify that no debris or extraneous combustible materials are present

anywhere (especially in the area of the burner and the gas controls); remove any

item

present and wipe clean the bottom of the housing.

5.

Inspect the interior surface of the housing for any cracks or corroded areas that could
allow penetration of gases into the interior of the vehicle. Check especially around the
Hot Water, Cold Water, Gas

and electrical connections.

6.

Check that all wire connections are firmly in place and there are no signs of chafing or
cracks on the wire insulation. Note that the spark ignition cable between the Circuit
Board and the igniter is securely in place and not shorted to any

metal component.

7.

At least once a year activate the Relief Valve by lifting the lever on top of the valve.

MAKE SURE THAT THE WATER HEATER HAS NOT BEEN ON RECENTLY AND THE
HOT WATER OUTLET IS COLD

.

8.

Turn on the power to the water heater and open a hot water faucet to inspect the flame
of the burner. The flame should be of the normal bluish appearance that indicates proper
combustion. This can be accomplished by observing the flames through the sight hole
and looking at the burner under the edge of the heat exchanger (See Figure

9.).

WINTERIZATION

Freezing of the water heater and its plumbing components will result in

severe damage that is
not covered by warranty. For this reason it is not advisable to use the standard unit (Part# 1GWH)
in the winter

without installing the Winter Use Device (See below for Winter Use Device

option).

At the start of the winter season or before traveling to a location where freezing conditions are
likely the unit must be winterized. The very small amount of water present in the heat exchanger
does not require the installation of a bypass

kit.
Winterization can be accomplished using one of the two common methods of winterization used
for RV

water systems:

•

Compressed Air Method:

Drain all water from the system opening one tap at a time

and using compressed air to purge all remaining water.

•

RV Anti-freeze Method:

Follow the recommendations of the Recreation Vehicle
manufacturer and fill the system with a non toxic anti-freeze. Make sure that the
antifreeze flows from each tap to complete the process.
