Gas Line Installation - Marquis Cove MQZDV3927N Installation Instructions Manual

Cove series vented gas fireplace heater

Table of Contents

This gas appliance should be installed by a qualified installer in accordance with local building codes and with current

CAN/CGA - B149.1 installation codes for Gas Burning appliances and equipment in Canada and the National Fuel Gas Code

ANSI Z223 in the U.S.A.

For the state of Massachusetts a T-handle gas shut-off valve must be used on a gas appliance. This T-handle gas shut-

off valve must be listed and approved by the state of Massachusetts. This is in reference to the state of Massachusetts

state code CMR238.

The gas pipeline can be brought in through either the left side of the

appliance. A knockout is provided at this location to allow for the gas

pipe installation and testing of any gas connection.

The gas control inlet is 3/8" NPT. Typical installation layout for rigid

pipe is shown at right.

When using copper or flex connector, use only approved fittings.

Always provide a union so that gas line can be easily disconnected for

burner or fan servicing. See gas specification for pressure details and

ratings.

When a vertical section of gas pipe is required for the installation, a

condensation trap is needed. See CAN/CGA-B149.1 for code details.

For natural gas, a minimum of 1/2" iron pipe with gas minimum pressure of 5.5" w.c. must be used for supply from the gas

meter. Consult with the local gas utility if any questions arise concerning pipe sizes.

Ports are accessible for test gauge connection both on the inlet and outlet of the gas valve.

Turn the gas supply ON and check for leaks. DO NOT USE OPEN FLAME FOR THIS PURPOSE. Use an approved leak

testing solution.

The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any

pressure testing of that system at test pressures in excess of 1/2psig [3.5 KPa].

The appliance must be isolated from the gas supply piping system by closing its individual shutoff valve during any

pressure testing of the gas supply piping system at test pressures equal to or less than 1/2psig [3.5 KPa].

Note: The gas line connection may be made of 1/2" rigid pipe, 1/2" copper pipe or an approved flex connector. Since some

municipalities have additional local codes, it is always best to consult your local authorities and the current CAN/CGA - B149.1

installation code in Canada or the National Fuel Gas code ANSI Z223.1 in the U.S.A.

IMPORTANT: Always check for gas leaks with a soap and water solution. DO NOT USE OPEN FLAME FOR LEAK TESTING.
