FDV451 / MQFDV453 Vertical Vent Installation

A firestop must be installed on the bottom side of the joists when passing through a ceiling or floor. If an attic insulation shield is to be

used, a firestop is not required.
One pair (two) 45° elbows may be used to provide an offset in order to avoid cutting of joists and to clear other obstructions.
When using 45° elbows, an elbow support is required directly above the highest elbow.
When installing a bend in a joist area a minimum of 2” clearance to combustible to the top of bend must be maintained, sides and

bottom of pipe, a 1” clearance to combustibles must be maintained. If running horizontally through an area, a 1” clearance to the top of

the horizontal pipe must be maintained.
Maximum vertical height of system should not exceed 45 feet.

Spacer springs to be installed on 4" flex pipe every 3 ft. on vertical runs. On 45° elbows or 90° elbows a spacer spring is needed on the

start of the bend and on the end of bend.

NOTE: You may be required to connect 2 lengths of flex pipe

together to achieve the desired length.

The parts are listed below:

ZDV4FC Flex Connector 4” diameter (needed to join 4” flex

together) and (4) screws.

Vertical Venting in Cold Climates

In cold climate conditions where temperatures go below -10°C [14°F], we recommend that the chase be insulated and where the vent pipe
enters into the attic space that the pipe be wrapped with an insulated Mylar sleeve. This will increase the temperature of the vent and help the
appliance to vent properly in cold weather conditions.

It is also important in vertical vented direct vent appliances that the appliance be operated daily during the winter months as this will help stop
the Termination from freezing up. We recommend using a thermostat set at room temperature to allow the unit to cycle.
For IPI models it may be necessary to set the appliance to Standing Pilot mode to maintain heat in the cavity. The purpose of this procedure is
to prevent cold air from penetrating the chimney and then onto the living space. Therefore, when the internal temperature is slightly elevated
the fireplace is able to freely exhaust its combustion and hence making it easier to startup.

An Attic Insulation Shield must be

installed where the vent passes from

a lower living space into an attic

space where the chimney is not

enclosed. It is designed to keep

insulation materials away from the

chimney.
When installing the Attic Insulation

Shield where the chimney passes

from a living space to an attic space,

install

the shield from below and

nail in place using 1" spiral nails.
