Exhaust Requirements section).

The dryer must be located in an area where correct exhaust

venting can be achieved as noted in this manual (refer to

Exhaust Requirements section).

IMPORTANT: The dryer should be located where a

minimum amount of exhaust ducting will be necessary.

The dryer must be installed with adequate clearance for air

openings into the combustion chamber.

CAUTION: This dryer produces combustible lint and

must be exhausted to the outdoors. Every 6 months,

inspect the exhaust ducting and remove any lint

buildup.

IMPORTANT: The dryer must be installed in a location/

environment, which the ambient temperature remains

between 40° F (4.44° C) and 130° F (54.44° C).

Unpacking / Setting Up ________________

Remove protective shipping material (i.e., plastic wrap and

optional shipping box) from the dryer.

IMPORTANT: Dryer must be transported and handled in an

upright position at all times.

The dryer can be moved to its final location while still attached

to the skid or with the skid removed. To remove the skid

from the dryer, locate and remove the 2 bolts securing the

base of the dryer to the wooden skid. One is located at the

center rear and the other is at the center front.

With the skid removed, use caution and assure all four

leveling legs are fully retracted, if the dryer is to be slid into

its final position.

Leveling Dryer

The dryer is equipped with 4 leveling legs, 1 at each corner

of the base. For optimum performance the dryer should be

level front-to-back and side-to-side.

Dryer Enclosure Requirements _______

113433-14 [email protected] 9

Fresh Air Supply Requirements ______

This appliance may only be installed in a room that meets

the appropriate ventilation requirements specified in the

national installation regulations.

When the dryer is operating, it draws in room air, heats it,

passes this air through the tumbler, and exhausts it out of

the building. Therefore, the room air must be continually

replenished from the outdoors. If the make-up air is

inadequate, drying time and drying efficiency will be adversely

affected. Ignition problems and sail switch “fluttering”

problems may result, as well as premature motor failure from

overheating. The dryer must be installed with provisions for

adequate combustion and make-up air supply.

Air supply (make-up air) must be given careful consideration

to ensure proper performance of each dryer. As a general

rule, an unrestricted air entrance from the outdoors of

110 inch2(710 cm2) is required for each dryer. (Based on

1 inch2[6.5 cm2] per 1,000 Btu [252 kcal].)

It is not necessary to have a separate make-up air opening

for each dryer. Common make-up air openings are

acceptable. However, they must be set up in such a manner

that the make-up air is distributed equally to all the dryers.

Exhaust Requirements ________________

Exhaust ductwork should be designed and installed by a

qualified professional. Improperly sized ductwork will create

excessive back pressure, which results in slow drying,

increased use of energy, and shutdown of the burner by the

airflow (sail) switch, burner hi-limits, or lint chamber hi-limit

protector thermostat. The dryer must be installed with a

proper exhaust duct connection to the outside.

The design of the flue system shall be such that any

condensate formed when operating the appliance from cold

shall either be retained and subsequently re-evaporated or

discharged.

CAUTION: This dryer produces combustible lint and

must be exhausted to the outdoors.

Improperly sized or installed exhaust ductwork can

create a potential fire hazard.

The ductwork should be laid out in such a way that the

ductwork travels as directly as possible to the outdoors with

as few turns as possible. There should be a minimum 6-inch

(15.24 cm) clearance between the back guard and the first

bend in the ductwork for ease of servicing. Single or

independent dryer venting is recommended. It is suggested

that the use of 90° turns be avoided; use 30° and/or 45° bends

instead. The radius of the elbows should preferably be

1-1/2 times the diameter of the duct. All ductwork should be

smooth inside with no projections from sheet metal screws

or other obstructions, which will collect lint. When adding

ducts, overlap the duct being connected. All ductwork joints

must be taped to prevent moisture and lint from escaping

into the building. Back draft dampers must be installed in all

commonly ducted systems. Inspection doors should be

installed at strategic points in the exhaust ductwork for

periodic inspection and cleaning of lint from the ductwork.

IMPORTANT: Exhaust back pressure measured by a

manometer/magnehelic in the exhaust duct must be no

less than 0 and must not exceed 0.6 in WC (1.5 mb) with

both tumblers operating.

NOTE: It is recommended that exhaust or booster fans not

be used in the exhaust ductwork system except where

necessary to maintain exhaust back pressure (in the

exhaust duct) between zero and 0.6 inch water column

with both tumblers operating. Where employed, booster

fans must not activate the dryer airflow proving switch (sail

switch) when the dryer is not in operation.

When the exhaust ductwork passes through a wall, ceiling,

or roof made of combustible materials, the opening must

be 2-inches (5.08 cm) larger than the duct (all the way

around). The duct must be centered within this opening.

As per the National Fuel Gas Code, “Exhaust ducts for

type 2 clothes dryers shall be constructed of sheet metal or

other noncombustible material. Such ducts shall be

equivalent in strength and corrosion resistance to ducts

made of galvanized sheet steel not less than 26 gauge

(0.0195-inches [0.50 mm]) thick.”

The ductwork for this appliance must be suitable for the

appliance category in accordance with national installation

regulations of the country of destination.

A = 14-inches (35.56 cm) B = 16-inches (40.64 cm)

EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings

measuring 14-inches by 16-inches (35.56 cm by 40.64 cm)

are acceptable.

To compensate for the use of registers or louvers used over

the openings, this area must be increased by approximately

33%. Make-up air openings should not be located in an area

directly near where exhaust vents exit the building.

Allowances must be made for remote or constricting

passageways or where dryers are located at high altitudes

or predominantly low pressure areas.

IMPORTANT: Make-up air must be free of dry cleaning

solvent fumes. Make-up air that is contaminated by dry

cleaning solvent fumes will result in irreparable damage to

the motors and other dryer components.

NOTE: Component failure due to dry cleaning solvent

fumes will void the warranty.

10 Girbau, SA 113433-14

Outside Ductwork Protection

To protect the outside end of the horizontal ductwork from

the weather, a 90° elbow bent downward should be installed

where the exhaust exits the building. If the ductwork travels

vertically up through the roof, it should be protected from the

weather by using a 180° turn to point the opening downward.

In either case, allow at least twice the diameter of the duct

between the duct opening and the nearest obstruction (refer

to the diagram).

IMPORTANT: Do not use screens, louvers, or caps on the

outside opening of the exhaust ductwork.

Single Dryer Venting

IMPORTANT: For extended ductwork runs, the cross-

sectional area of the ductwork can only be increased to an

extent. When the ductwork approaches the maximum

limits as noted in this manual, a professional HVAC firm

should be consulted for proper venting information.

NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)

larger than the duct (all the way around). The duct must be centered

within this opening.

NOTE 2 Distance should be 2 times the diameter of the duct to the nearest

obstruction.

A = 12 feet (3.66 meters)

B = 8-inches (20.32 cm)

The length of the ductwork from the dryer to the outside

exhaust outlet, must not exceed 12 feet (3.66 meters). The

minimum diameter of this ductwork must be at least

8-inches (20.32 cm) even though the dryer exhaust duct

connection is smaller. Including tumbler/dryer elbow

connections or elbows used for outside protection from the

weather, no more than 4 90° elbows should be used in the

exhaust duct run. If more than the equivalent of 4 90° elbows

are used, the cross-sectional area of the ductwork must be

increased.

Multiple Dryer (Common) Venting

IMPORTANT: For extended ductwork runs, the cross-

sectional area of the ductwork can only be increased to an

extent. When the ductwork approaches the maximum

limits as noted in this manual, a professional HVAC firm

should be consulted for proper venting information.

If it is not feasible to provide separate exhaust ducts for each

dryer, ducts from individual dryers may be channeled into a

“common main duct.” The individual ducts should enter the

bottom or side of the main duct at an angle not more than

45º in the direction of airflow. The main duct should be

tapered, with the diameter increasing before each individual

duct is added. The minimum diameter of the individual

ductwork must be at least 8-inches (20.32 cm).

IMPORTANT: No more than four dryers should be

connected to one main common duct.

NOTES _____________________________________________________

____________________________________________________________

113433-14 [email protected] 11

The illustration below shows the minimum cross-sectional

area for multiple dryer round or square venting. These figures

must be increased if the main duct run from the last dryer to

where it exhausts to the outdoors is longer than 12 feet (3.656

meters) or has more than 1 elbow in it.

Multiple Dryer Venting with 8-Inch (20.32 cm) Diameter

720 cfm (20.39 cmm) Exhaust Connections at Common Duct

NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)

larger than the duct (all the way around). The duct must be centered

within this opening.

NOTE 2 Distance should be 2 times the diameter of the duct to the nearest

obstruction.

Piping / Connections

The dryer is provided with two 3/8” N.P.T. (3/8” B.S.P.T. for

CE dryers) inlet pipe connections (1 for each tumbler) at the

rear of the dryer. If a separate feed is provided for each

tumbler from the main supply line (header), then a 1/2” (12.7

mm) line connection is sufficient. However, if the top and

bottom tumbler connections are connected together, the

supply from the header must be increased to 3/4-inch (19.05

mm). There should be a minimum 6-inch (15.24 cm)

clearance between the back guard and the first bend in the

gas piping for ease of servicing. It is recommended that a

gas shutoff valve be provided to the gas supply line of each

dryer for ease in servicing.

Installer withinAustralia – refer to AS/NZS5601.1 for guidance

on gas supply pipe sizing required for this appliance

installation.

The size of the main gas supply line (header) will vary

depending on the distance this line travels from the gas meter

or, in the case of L.P. gas, the supply tank, other gas-operated

appliances on the same line, etc. Specific information

regarding supply line size should be determined by the gas

supplier.

NOTE: Undersized gas supply piping can create a low or

inconsistent pressure, which will result in erratic operation

of the burner ignition system.

TYPICAL NATURAL GAS INSTALLATION

Consistent gas pressure is essential at all gas connections.

It is recommended that a 3/4-inch (19.05 mm) pipe gas loop

be installed in the supply line servicing a bank of dryers. An

in-line pressure regulator must be installed in the gas supply

line (header) if the (natural) gas pressure exceeds 13.0 in

WC (32.34 mb) pressure.

A plugged tap, accessible for a pressure gauge connection,

must be installed in the main gas supply line immediately

upstream of the dryers.

Gas Pressure Testing _________________

For proper operation, the gas pressure must be correct,

consistent and maintained at the gas pressure rates shown

on page 15. Provisions are made at the gas valve for taking

gas pressure readings.

There are two types of devices used to measure gas pressure.

They are the spring/mechanical type gauge and the

manometer. The use of the spring/mechanical type gauge is

not recommended because they are very easily damaged

and are not always accurate. The preferred type of gauge is

the manometer because it is a simple device to use and is

highly accurate. Amanometer is simply a glass or transparent

plastic tube with a scale graduated in inches or millibars.

When it is filled with water and pressure is applied, the water

in the tube rises, showing the exact gas pressure.

Gas Pressure Test Procedure

Turn gas cock in gas supply line to “OFF” position.

50 Hz dryers: Back out miniature screw inside pressure tap

and attach manometer (refer to the illustration on page 17).

60 Hz dryers: Install pressure tap and attach manometer (refer

to the illustration on page 17).

Turn gas cock to “ON” position.

Start the dryer in Heat Mode and wait for ignition. Gas

manifold pressure should be as shown on page 15.

If the gas pressure needs to be adjusted, refer to “Gas

Pressure Adjustment” on this page.

Once test is complete, turn gas cock to “OFF” position.

Remove manometer. Tighten screw inside the pressure tap

or install plug.

Turn gas cock to “ON” position and check for leaks with soap

solution with main burner “ON.”

Edge #1 for vent cap

Edge #2 for adjustment screw

Select from the following 3 options, the conversion to be

performed:

•Converting from unregulated L.P. to regulated

natural gas: use a flat screwdriver to remove the cap

with blocking pin and install the regulator vent cap from

the kit (P/N 140415).

•Converting from unregulated L.P. to unregulated

natural gas: no change to the regulator is required.

•Converting from regulated L.P. to regulated natural

gas: remove the white plastic regulator adjustment

screw (under vent cape). Remove spring under screw

and replace with spring from kit (P/N 140415). Replace

regulator adjustment screw.

Install the gas train back into the dryer gas train enclosure.

Be sure the tab at the rear of the gas train engages into the

mounting slot.

Connect the union and the 3 electrical plugs.

Repeat these steps for the other burner.

Open all shutoff valves, reconnect electrical power to the

dryer, and test for leaks.

Operate the dryer through 1 complete cycle to ensure proper

operation.

With dryer operating, check the manifold (burner) pressure

at the tap on the gas valve to ensure proper operating

pressure (refer to chart on page 15).

Gas Pressure Adjustment

Disconnect electrical power to the dryer.

IMPORTANT: The following procedures must be performed

on both top and bottom tumblers.

To adjust gas valve’s internal regulator, remove the regulator

vent cap with the regulator adjustment tool, which is located

on the back guard between the gas inlet and exhaust outlet

(refer to the illustration below for proper use of adjustment

tool). Be sure to use one of the wide ends of the adjustment

tool for removal of the vent cap. Once vent cap is removed,

the narrow end of the adjustment tool can be used to turn the

plastic adjustment screw in the valve. Turn the screw

clockwise to raise pressure and counterclockwise to lower

pressure.

Gas (burner) pressures are measured with the burner in

operation for all burner adjustment conditions. Therefore

once the necessary adjustments have been made, the dryer

must be operated in a heating cycle to verify that the pressure

is correct. If it is not correct, you must discontinue the power

to the unit and make further adjustments. Repeat these steps

as many times as necessary to achieve the correct burner

pressure. Once the adjustment of the valve is complete, the

vent cap must be replaced and sealed with, for example,

paint to prevent maladjustment by the user.

!WARNING (CE Dryers)

This appliance must only be operated with the gas

type indicated on the dryer’s data plate. If the

appliance is converted (gas type changed), a data

plate amendment must be obtained from Girbau.

Conversions done improperly can result in a fire or

explosion!

Steam Information ____________________

It is your responsibility to have all plumbing connections made

by a qualified professional to ensure that the steam plumbing

installation is adequate and conforms with local, state, and

country regulations or codes.

Care must be exercised when leveling steam dryers into final

position. After leveling the dryer, check the downward pitch

of the heat exchanger from front to rear with a level. Likewise,

check the downward pitch of the return condensate manifold

toward its outlet part. Absence of these downward pitches

will result in probable water hammer and premature heat

exchanger fracture and leakage.

The presence of condensate in the steam will cause water

hammer and subsequent heat exchanger failure. The steam

supply connection must be taken from the top of a

well-dripped steam main. If the supply run-out to the dryer

exceeds 25 feet (7.6 meters), it should be dripped just before

the control valve with a proper trap and dirt pocket.

IMPORTANT: Failure to comply with the requirements

stipulated in this manual can result in component failure,

which will void the warranty.

Steam Coil pH Level

The normal pH level for copper type steam coils must be

maintained between a value of 8.5 to 9.5. For steel type

steam coils the pH level must be maintained between a value

of 9.5 to 10.5. These limits are set to limit the acid attack of

the steam coils.

IMPORTANT: Coil failure due to improper pH level will void

the warranty.

Steam Requirements – High Pressure

Shaded areas are stated in metric equivalents

* The minimum operating pressure for optimum results is 100 psig (689.47

kPa).

Installation Instructions

To ensure an adequate supply of steam is provided, be sure

that the steam supply lines and steam return lines are sized

and laid out as stipulated in this manual. Inadequate steam

supply lines and steam return lines or improper steam

plumbing will result in poor performance and can cause

component failure. Clean, dry steam must be provided to

the dryer.

IMPORTANT: Steam coil failure due to water hammer by

wet steam will void the warranty.

The presence of condensate in the steam supply line will

cause water hammer and subsequent heat exchanger (steam

coil) failure. The steam supply connection into the main

supply line must be made with a minimum 10-inch (25.4 cm)

riser. This will prevent any condensate from draining towards

the dryer.

The steam supply line to the dryer must include a 12-inch

(30.48 cm) riser along with a drip trap and check valve. This

will prevent any condensate from entering the steam coil.

Water Information _____________________

Before You Start

Check Local Codes and Permits

Call your local water company or the proper municipal

authority for information regarding local codes.

IMPORTANT: It is your responsibility to have all plumbing

connections made by a qualified professional to ensure

that the plumbing installation is adequate and conforms to

local, state, and federal regulations or codes.

It is the installer’s or owner’s responsibility to see that the

required water pressure, pipe size, or connections are

provided. The manufacturer assumes no responsibility if

the fire suppression system is not connected, installed, or

maintained properly.

Installation

Water Supply

The fire suppression system must be supplied with a minimum

water pipe size of 1/2-inch (12.7 mm) and be provided with

40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure.

If the rear area of the dryer or the water supply is located in

an area where it will be exposed to cold/freezing

temperatures, provisions must be made to protect these water

lines from freezing.

Flexible hoses or couplings must be used. The dryer vibrates

slightly when it runs and this will cause the steam coil

connections to crack if they are hard piped to the supply and

return mains.

Shutoff valves for each dryer should be installed in the supply

line, return line, and drip trap return line. This will allow the

dryer to be isolated from the supply main and the return main

if the dryer needs maintenance work.

Install an inverted bucket steam trap and check valve at least

12-inches (30.48 cm) below the steam coil as close to the

coil as possible. A trap with a minimum capacity of 100 lb

(45.35 kg) of condensate per hour at 125 psi (8.62 bar) is

needed for each unit. (Based on 2 times the steam

consumption per hour.)

The supply line and the return line should be insulated. This

will save energy and provide for the safety of the operator

and maintenance personnel.

Water pockets in the supply line, caused by low points, will

provide wet steam to the coil possibly causing steam coil

damage. All horizontal runs of steam supply piping should

be pitched 1/4-inch (6.35 mm) for every 1 foot (0.31 meters)

back towards the steam supply header causing the

condensate in the line to drain to the header. Install a bypass

trap in any low point to eliminate wet steam.

IMPORTANT: Flexible hoses/couplings must be used. Coil

failure due to hard plumbing connections will void the

warranty.

!WARNING

If the water in the supply line or water solenoid valve

freezes, the fire suppression system will be

inoperative!!

Water Connections

The water connection is made to the 3/4”-11.5 NH hose

adaptor, which is shipped in the tumbler and must be installed

to the 1/2” N.P.T. water connection, located at the upper rear

of the dryer. A flexible supply line/coupling must be used in

an effort to avoid damaging the electric water solenoid valve.

NOTE: The 3/4”-11.5 NH is a standard hose coupling

screw thread. It is not to be confused with 3/4” N.P.T. The

sealing of an NH connection is made with a washer

opposed to the mating threads of an N.P.T. assembly. The

two thread designs are not compatible.

It is recommended that a filter or strainer be installed in the

water supply line.

IMPORTANT: Flexible supply line/coupling must be used.

Solenoid valve failure due to hard plumbing connections

will void warranty.

The dryer is to be connected to the water mains using a

new hose set and the old hose set should not be reused.
