GENERAL INFORMATION

Note: Installation and repair should be performed by a qualified
service person. The appliance should be inspected annually by a
qualified professional service technician. More frequent inspections
and cleanings may be required due to excessive lint from carpeting,
bedding material, etc. It is imperative that the control compartment,
burners and circulating air passage ways of the appliance be kept
clean.
S'assurer que le brùleur et le compartiment des commandes sont
propres. Voir les instructions d'installation et d'utilisation qui
accompagnent l'appareil.
Provide adequate clearances around air openings and adequate acces-
sibility clearance for service and proper operation. Never obstruct the
front openings of the appliance.
These appliances are designed to operate on natural or propane
gas only.
These millivolt models come standard with the manually-modulated
gas valve; flame appearance and heat output can be controlled at
the gas valve.
These appliances are designed as supplemental heaters. Therefore,
it is advisable to have an alternate heat source when installed in a
dwelling.

Installations at Altitudes of 0 to 4500 feet - Units are tested and
approved for elevations of 0 to 4500 feet (0 to 1370 meters).
Installations at Altitudes above 4500 ft.-
For elevations above 4500 feet (1370 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
CAN/CSA-B149.1 and CAN-B149.2 codes.
Table 4 shows the units' gas orifice size for the elevations
indicated:
The millivolt appliances are manually controlled and feature a spark
igniter (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. Imme-
diately call a qualified, professional service technician to inspect
the appliance and to replace any parts of the control system and any
gas controls which have been under water.
Ne pas se servir de cet appareil s'il a été plongé dans l'eau, com-
plètement 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.

Test gauge connections are provided on the front of the millivolt gas
control valve (identified IN for the inlet and OUT for the manifold
side).
Propane tanks are at pressures that will cause damage to valve com-
ponents. Verify that the tanks have step down regulators to reduce the
Maximum

These appliances must be isolated from the gas supply piping
system (by closing their individual manual shut-off valve) during
any pressure testing 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 testing of that system at pressures greater than 1/2
psig (3.5 kPa).
