Installing Flue Components

1.Attach the First Flue Component to the Starting Collars

To attach the first flue component to the starting collars of the fireplace:

Apply a 3/8 inch (10mm) bead of stove cement around the inner pipe heater starting collar.

Make sure that the heater rope gasket supplied with the heater seals between the first flue component and the outer heater wrap.

Lock the flue components into place by sliding the concentric pipe sections with four (4) equally spaced interior beads into the heater collar or previously installed component end with four (4) equally spaced indented sections.

When the internal beads of each outer pipe line up, rotate the pipe section clockwise about onequarter (1/4) turn. The flue pipe is now locked together.

The first 90° elbow installed in the flue system of a rear flueing heater MUST BE in a vertical position.

!WARNING: ENSURE THAT THE FIBERGLASS ROPE GASKET SUPPLIED WITH THE HEATER SEALS BETWEEN THE FIRST FLUE COMPONENT AND THE OUTER HEATER WRAP.

2.Continue Adding Flue Components

To continue adding flue components in accordance with the pre-plannedflue system configuration:

Ensure that each succeeding flue component is securely fitted and locked into the preceding component in the flue system.

90° elbows may be installed and rotated to any point around the preceding component’s vertical axis. If an elbow does not end up in a locked position with the preceding component, attach with a minimum of two (2) sheet metal screws.

3. Install Support Brackets

Figure 11 Attaching the First Flue Component to the Starting Collars

! WARNING: A 3/8 INCH (10MM) BEAD OF STOVE CEMENT MUST BE PLACED AROUND THE INNER PIPE HEATER STARTING COLLAR BEFORE ATTACHING THE FIRST FLUE COMPONENT. FAILURE TO SEAL THIS JOINT MAY CAUSE THE HEATER TO OPERATE IMPROPERLY. SEE FIGURE 11.

Figure 12 Adding Flue Components

For Horizontal Runs - The flue system must be supported every five (5) feet of horizontal run by a horizontal pipe support.

To install support brackets for horizontal runs:

Place the pipe supports around the flue pipe.

Nail the pipe supports to the framing members.

14

For Vertical Runs

The flue system must be supported every eight

(8) feet (2.4M) above the heater flue outlet by wall brackets.

To install support brackets for vertical runs:

• Attach wall brackets to the flue pipe and secure the wall bracket to the framing members with nails or screws.

Use wall brackets to support vertical runs every 8 feet (2.4M) above the heater flue outlet.

4. Install Firestops

For Horizontal Runs - Firestops are REQUIREDon both sides of a combustible wall through which the flue passes.

To install firestops for horizontal runs that pass through either interior or exterior walls:

Cut a 12-inchby12-inch(305 mm X 305 mm) hole through the wall. The center of the hole is one (1) inch (25mm) above the center of the horizontal flue pipe.

Position the firestops on both sides of the hole previously cut and secure the firestops with nails or screws.

The heat shields of the firestops MUST BE placed towards the top of the hole.

Continue the flue run through the firestops.

Firestops

For Vertical Runs - One ceiling firestop isREQUIRED at the hole in each ceiling through which the flue passes.

To install firestops for vertical runs that pass through ceilings:

Position a plumb bob directly over the center of the vertical flue component.

Mark the ceiling to establish the centerpoint of the flue.

15

Drill a hole or drive a nail through this center point.

For Vertical Terminations - To locate the flue and install the flue sections:

Locate and mark the flue center point on the underside of the roof, and drive a nail through the center point.

Make the outline of the roof hole around the center point nail.

The size of the roof hole framing dimensions depend on the pitch of the roof. There MUST BE a1-inch(25mm) clearance from the vertical flue pipe to combustible materials.

Mark the roof hole accordingly.

Cover the opening of the installed flue pipes.

Cut and frame the roof hole.

Use framing lumber the same size as the roof rafters and install the frame securely. Flashing anchored to the frame must withstand heavy winds.

Continue to install concentric flue sections up through the roof hole and up past the roof line until you reach the appropriate distance above the roof.

CAUTION: FOLLOW THE REQUIREMENTS OF THE AGA GAS INSTALLATION CODE FOR MINIMUM HEIGHT REQUIREMENTS ABOVE THE ROOF.

To seal the roof hole, and to divert rain and snow from the flue system:

Attach a flashing to the roof using nails, and use a non-hardeningmastic around the edges of the flashing base where it meets the roof.

Attach a storm collar over the flashing joint to form a water-tightseal. Placenon-hardeningmastic around the joint, between the storm collar and the vertical pipe.

1.8 INSTALLER TESTING

The space heater must be tested and be operating according to manufacturers specifications prior to the installer leaving the site. Note: the tips of the flames should never hit the top of the firebox after the unit has warmed up. Please contact your dealer or a qualified service person to replace injector or adjust valve.

Upon completing the gas line connection, a small amount of air will be in the lines. When first lighting the pilot light, it will take a few minutes for the lines to purge themselves of this air. Once the purging is complete, the pilot and burner will light and operate as indicated in the Lighting Instructions.

Subsequent lightings of the appliance will not require such purging.

CAUTION: DURING THE INITIAL PURGING AND SUBSEQUENT LIGHTINGS, NEVER ALLOW THE GAS VALVE CONTROL KNOB TO REMAIN DEPRESSED IN THE "PILOT" POSITION WITHOUT PUSHING THE RED IGNITOR BUTTON AT LEAST ONCE EVERY SECOND.

Follow the Safety Information and Lighting Instructions pages of this manual to light the appliance.

To obtain proper operation, it is imperative that the pilot and main burner flame characteristics are steady, not lifting or floating. Typically, the top 3/8-inch(10mm) at the pilot generator should be engulfed in the pilot flame. (Figure 26.)

Standing Pilot

FIGURE 27

2.0 OPERATING INSTRUCTIONS

This appliance is a balanced flue heater and is designed to operate with all combustion air being siphoned from the outside of the building and all exhaust gases expelled to the outside of the building.

! WARNING: THIS UNIT IS NOT FOR USE WITH SOLID FUEL.

The control system for these models is a millivolt type. It consists of a gas control valve/variable regulator, a standing pilot assembly, a thermopile/thermocouple assembly, a piezo ignitor, an ON/OFF rocker switch, and a safety high temperature limit switch. The controls are located in the lower compartment behind the lower grille. Access to this compartment is gained by rotating the grille up. See Figure 1.

! WARNING: DO NOT CONNECT220-240VAC TO THE GAS CONTROL VALVE OR CONTROL WIRING SYSTEM OF THIS UNIT.

The gas control system is wired so the thermopile, when heated with the pilot light, will provide approximately 350 to 500 millivolts. This activates the gas control valve. See Figure 28 for appliance wiring diagram.

When lit for the first time, the appliance will emit a slight odor for an hour or two. This is due to paint and lubricants used in the manufacturing process. Additionally, for the first few minutes after each lighting, vapor may condense and fog the glass and the flames may be blue. After a few minutes this moisture will disappear and within 15-30minutes the flames should become yellow.

The heater may produce a noise, caused from metal expansion and contraction as it heats up and cools down. This noise is similar to one that a furnace or heat duct may produce and does not affect the operation or longevity of the heater.

3.5TROUBLESHOOTING - ST-38HV-AU

With proper installation and maintenance, your new heater should provide years of trouble-freeservice. If you do experience a problem, refer to the Troubleshooting Guide below. This guide will assist a qualified service person in the diagnosis of problems and the corrective action to be taken.

SYMPTOM

POSSIBLE CAUSE

CORRECTIVE ACTION

I.Spark Ignitor will not light pilot after repeated triggering of red button.

II.Pilot will not stay lit after carefully following lighting instructions.

A.Defective ignitor (no spark at electrode).

B.Defective pilot or misaligned electrode (spark at electrode).

C. No gas or low gas pressure.

A. Defective thermocouple.

1.Check for spark at electrode and pilot; if no spark and electrode wire is properly connected, replace ignitor.

1.Using a match, light pilot. If pilot lights, turn off pilot and trigger the red button again. If pilot lights, an improper gas/air mixture caused the bad lighting and a longer purge period is recommended. If pilot will not light - check gap at pilot - should be 1/8 inch (3.2mm) to have a strong spark.

If OK, replace pilot.

1.Check unit's shut-offvalve and remote shut off valves from heater. Usually there is a valve near the main. There can be more than one (1) valve between the heater and main.

2.Low pressure can be caused by a variety of situations such as a bent line, too narrow diameter of pipe or even low line pressure. Check for kinked lines. If none, consult with plumber or gas supplier.

1.Check pilot flame. Must impinge on thermocouple. Clean and or adjust pilot for maximum flame impingement on thermocouple.

2.Be sure wire connections from thermocouple at gas valve terminals are tight and thermopile is fully inserted into pilot bracket.

28

SYMPTOM

POSSIBLE CAUSE

III.Pilot burning, no gas burner, valve knob "ON", "on-off"switch "ON".

B.Open wire connection in pilot circuit.

C.Defective valve.

A."ON-OFF"switch or wires defective.

B.Thermopile may not be generating sufficient millivoltage. (325m.v.)

CORRECTIVE ACTION

3.Check thermopile with millivolt meter. Take reading at “THTP&TP” terminals of gas valve. Should read 325 millivolts minimum while holding valve knob depressed in pilot position, pilot lit, and on/off switch “OFF”. Replace faulty thermocouple if reading is below specified minimum.

4.Disconnect thermopile leads from the valve. With pilot burner "ON", take reading at thermopile leads - should read 325 millivolts minimum. Replace thermopile if reading is below this minimum.

1.Check wire continuity and connection in pilot circuit.

1.Disconnect the thermopile's red wire from the micro-switchand connect to terminal "TP" on the gas valve. Turn green knob to pilot position, depress and light pilot light. If meter reading is greater than 325 m.v. after 30 seconds, the pilot generator is good. If pilot does not stay lit, the valve is defective. If the meter reading is less than 325 m.v., the thermopile is defective.

1.Check "on-off"switch and wires for proper connections. Place jumper wires across terminals atswitch-ifburner comes on, replace defective switch. If OK, place jumper wires across switch wires at gasvalve-ifburner comes on, wires are faulty or connections are bad.

1.Recheck Symptom #2.

2.Pilot flame not physically close enough to thermopile.

29

SYMPTOM

IV. Frequent pilot outage problem.

V.Pilot and main burner go out while being in operation.

POSSIBLE CAUSE

C. Defective valve.

D.Plugged burner orifice.

E.Wall switch or wires defective.

A.Pilot flame may be too low or blowing (high), causing the pilot safety to drop out.

A.High limit switch is defective or has reached its maximum temperature.

B.Inner 5-inch(13mm) pipe leaking exhaust gases back into system.

C.Horizontal flue improperly pitched.

CORRECTIVE ACTION

1.Turn valve knob to “ON”. Place ON/OFF switch to “ON”. Check with millivolt meter at thermopile terminals. Millivolt meter should read greater than 100 m.v. If the reading is okay and the burner does not come on, replace the gas valve.

1.Check burner orifice for stoppage and remove.

1.Follow corrective action in A.1 above; check switch and wiring. Replace where defective.

1.Clean and adjust pilot flame for maximum flame impingement on thermopile.

1.Allow unit to cool. Then repeat lighting instructions. If pilot and burner remain lit after the heater warms up, the switch is good.

2.If 1 above does not allow for ignition, or the heater continues to shut-off,disconnect the limit switch wire from the gas valve and repeat the lighting instructions. If the pilot and burner remain lit after the heater warms up, replace the limit switch.Do not use the heater until the high limit switch is replaced and properly wired.

1. Check for leaks.

1.Horizontal flue termination should slope down only enough to prevent water from entering unit. The maximum downward slope is 1/4" (6.4mm) for any horizontal run.
