Installation must conform to local codes. In the

absence of local codes, installation must comply

with the current National Fuel Gas Code, ANSI

Z223.1. (In Canada, the current CAN-1 B149

installation code).

The appliance, when installed, must be elec-

trically grounded & wired in accordance with

local codes or, in the absence of local codes,

with the National Electrical Code, ANSI / NFPA

70-latest  edition,  or  the  Canadian  Electrical

Code, CSA C22.1 - latest edition.

Provide adequate clearances around air open-

ings and adequate accessibility clearance for

service and proper operation. Never obstruct

the front openings of the appliance.

These fireplaces are designed as supplemen-

tal heaters. Therefore, it is advisable to have

an  alternate  heat  source  when  installed  in  a

dwelling.

Millivolt Models - 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.

Millivolt models come standard with a manu-

ally-modulated gas valve; flame appearance and

heat output can be controlled at the gas valve.

The BTU Input for these appliances is shown

in Tables 1 & 2.

The  Millivolt  appliances  have  a  millivolt  gas

control valve with piezo ignition system which

provides safe, efficient operation. If any optional

accessories  that  will  require  electrical  power

are to be installed, the electrical power must be

provided at the time of appliance installation.
The

Electronic appliances have an electronic

intermittent pilot ignition system which provides

safe, efficient operation. External electrical pow-

er is required to operate these appliances.
