Operation and Care of Your Appliance

Millivolt appliances may be fitted at time of manufacture with either a Robertshaw millivolt gas control valve or Robertshaw electronic gas control valve. Both valves have been tested with and approved for use with these appli- ances and are listed accordingly.

A ¹⁄₈" NPT test gage connection is provided on either gas control valve adjacent to the outlet to the main burner.

Minimum inlet gas pressure to the appliance is

4.5inches water column (8.55 MmHg) for natural gas and 11 inches water column (20.55 MmHg) for propane for the purpose of input adjustment.

Maximum inlet gas supply pressure to the appliance is 10.5 inches water column (19.95 MmHg) for natural gas and 13.0 inches water column (24.25 MmHg) for propane.

The appliance must be isolated from the gas supply piping system (by closing its individual manual shut-off valve) during any pressure test- ing of the gas supply piping system at test pressures equal to or less than ¹⁄₂ psig (3.5 kPa).

The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at pressures in excess of ¹⁄₂ psig (3.5 kPa).

These appliances must not be connected to a chimney or flue serving a separate solid fuel burning appliance.

WARNING: FAILURE TO COMPLY WITH THE INSTALLATION AND OPERATING IN- STRUCTIONS PROVIDED IN THIS DOCU- MENT WILL RESULT IN AN IMPROPERLY INSTALLED AND OPERATING APPLI- ANCE, VOIDING ITS WARRANTY. ANY CHANGE TO THIS APPLIANCE AND/OR ITS OPERATING CONTROLS IS DANGER- OUS. IMPROPER INSTALLATION OR USE OF THIS APPLIANCE CAN CAUSE SERI- OUS INJURY OR DEATH FORM FIRE, BURNS, EXPLOSION OR CARBON MON- OXIDE POISONING.

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning are similar to the flu with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air immediately. Turn off the gas supply to the appliance and have it serviced by a qualified professional, as it may not be op- erating correctly.

WARNING: B-VENT APPLIANCES ARE NOT DESIGNED TO OPERATE IN NEGATIVELY PRESSUREDENVIRONMENTS(PRESSURE WITHIN THE HOME IS LESS THAN PRES- SURES OUTSIDE). SIGNIFICANT NEGA- TIVELY PRESSURED ENVIRONMENTS CAUSED BY WEATHER, HOME DESIGN, OR OTHER DEVICES MAY IMPACT THE OPERATION OF THESE APPLIANCES. NEGATIVE PRESSURES MAY RESULT IN POOR FLAME APPEARANCE, SOOTING, DAMAGE TO PROPERTY AND/OR SEVERE PERSONAL INJURY. DO NOT OPERATE THESEAPPLIANCESINNEGATIVELYPRES- SURED ENVIRONMENTS.

WARNING: CHILDREN AND ADULTS SHOULD BE ALERTED TO THE HAZARDS OF HIGH SURFACE TEMPERATURES. USE CAUTION AROUND THE APPLIANCE TO AVOID BURNS OR CLOTHING IGNITION. YOUNG CHILDREN SHOULD BE CARE- FULLY SUPERVISED WHEN THEY ARE IN THE SAME ROOM AS THE APPLIANCE.

WARNING: DO NOT PLACE CLOTHING OR OTHER FLAMMABLE MATERIALS ON OR NEAR THIS APPLIANCE.

AVERTISSEMENT: SURVEILLER LES ENFANTS. GARDER LES VÊTEMENTS, LES MEUBLES, L'ESSENCE OU AUTRES LIQUIDES À VAPEUR INFLAMMABLES LIN DE L'APPAREIL.

Appliance operation must be controlled through a remotely located wall switch (factory-sup- plied). Separate switches may provide inde- pendent control for the remote controlled fire- place operation (optional equipment).

Control Compartment Access - GRD-5500 Units

The lower control compartment access panel has been designed to cover the control com- partment from view. Lighting instructions are displayed on the back side of the cover for easy reference. To attach the panel to the appliance, hook both ends of the panel over the two brackets mounted on each side of the front combustion opening. The cover should hang from the brackets with the flared edge at the bottom allowing for a small air gap between the cover and the appliance. To remove, lift the panel and pull away from the unit.

Control Compartment Access - GHC-5500 Units

The GHC lower control compartment access is provided by removing the three louvers .

To remove the louvers, pull them straight out from the unit. To replace, tilt each of them with the top edge over the top of each peg and snap the lower edge to lock in place. See Figure 2.
