Millivolt Models -
Millivolt models come standard with the manually-modulated gas valve; flame ap- pearance and heat output can be con- trolled at the gas valve.
Input of millivolt models is shown in the following table:

Electronic Models -
Electronic models have a fixed rate gas valve. Input of electronic models is shown in the following table:
Electronic Models with Fixed-Rate Gas Valve

D, DT, DR Series | Input rate (BTU/H) |
500 | 23,000 |
600 | 29,000 |
800 | 32,000 |
All Models -
Maximum manifold pressure is 3.5 in. w.c. (0.87 kPa) for natural gas and 10 in. w.c. (2.49 kPa) for LP/Propane gas.
Installations at Altitudes of 0 to 4500 ft.- Units are tested and approved for elevations of 0 to 4500 feet (0 to 1372 meters).
Installations at Altitudes above 4500 ft.- For elevations above 4500 feet (1372 meters), install the unit according to the regulations of the local authorities having jurisdiction and, in the USA, the latest edition of the National Fuel Gas Code (ANSI Z223.1) or, in Canada, the latest edition of the CAN1-B149.1 and .2 codes.
Table 1 shows the units' gas orifice size for the elevations indicated.

The millivolt appliances are manually controlled and feature a spark ignitor (piezo) that allows the appliance's pilot gas to be lit without the use of matches or batteries. This system provides continued service in the event of a power outage.
Do not use these appliances if any part has been under water. Immediately call a quali- fied, professional service technician to inspect the appliance and to replace any parts of the control system and any gas control which have been under water.
Ne pas se servir de cet appareil s'il a été plongé dans l'eau, complètement ou en partie. Appeler un technicien qualifié pour inspecter l'appareil et remplacer toute partie du système de contrôle et toute commande qui ont été plongés dans l'eau.
This appliance may be installed in an af- termarket permanently located, manufac- tured home (USA only) or mobile home, where not prohibited by local codes. This appliance is only for use with the type of gas indicated on the rating plate. This ap- pliance is not convertible for use with other gases, unless a certified kit is used.
Cet appareil peut être installé dans un maison préfabriquée (É.-U. seulement) ou mobile déjà installée à demeure si les réglements locaux le permettent.
Cet appareil doit être utilisé uniquement avec les types de gaz indiqués sur la plaque signalétique. Ne pas l'utiliser avec d'autres gaz sauf si un kit de conversion certifié est installé.
Test gage connections are provided on the front of the millivolt gas control valve (iden- tified IN for the inlet and OUT for the mani- fold side). A ¹⁄₈" NPT test gage connection is provided at the inlet and outlet side of the electronic gas control valve.
Minimum inlet gas pressure to these appliances is 5.0 inches water column (1.24 kPa) for natural gas and 11 inches water column (2.74 kPa) for propane for the purpose of input adjustment.
Maximum inlet gas supply pressure to these appliances is 10.5 inches water column (2.61 kPa) for natural gas and 13.0 inches water column (3.23 kPa) for propane.
These appliances must be isolated from the gas supply piping system (by closing their 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).
These appliances and their individual shut-off valves must be disconnected from the gas supply piping system during any pressure test- ing 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.
Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning are similar to the flu with headaches, dizziness and/or nau- sea. 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 operating correctly.
WARNING: FAILURE TO COMPLY WITH THE INSTALLATION AND OPERATING IN- STRUCTIONS PROVIDED IN THIS DOCU- MENT WILL RESULT IN AN IMPROP- ERLY INSTALLED AND OPERATING AP- PLIANCE, 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 FROM FIRE, BURNS, EXPLOSION OR CARBON MON- OXIDE POISONING.
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
ÀCOTE DE L'APPAREIL.
LOCATION
In selecting the location, the aesthetic and func- tional use of the appliance are primary concerns. However, vent system routing to the exterior and access to the fuel supply are also important. Consideration should be given to traffic ways, furniture, draperies, etc., due to elevated surface temperatures (see Figure 2 ).
