LENNOX HEARTH PRODUCTS • RHAPSODY™ LINEAR DIRECT-VENT GAS FIREPLACES (MODEL RHAP54N) • INSTALLATION INSTRUCTIONS

GENERAL

INFORMATION

INTRODUCTION

LENNOX HEARTH PRODUCTS Rhapsody™

models are direct-vent (top vent only), sealed

combustion, air-circulating gas fireplaces

designed for residential applications.

Direct-vent appliances operate with the com-

bustion chamber isolated from the indoor

environment. All air for combustion is brought

in from the outside, and exhaust gases are

vented through the same direct-vent, coaxial

(intake/exhaust) vent system.

These appliances are designed to operate

on natural or propane gas only. The use of

other fuels or fuel combinations will degrade

the performance of this system, may be

dangerous, and may void the warranty.

The electronic system is switchable between

standing and intermittent pilot modes (see

Figure 11-2).

The Total Comfort Control™Remote Control

System is included with all models and provides

remoteoperationofseveralreplacefunctions

(manual adjustment of the gas valve settings is

not possible). See Page 25 for details.

Electrical power (110 Vac line voltage) is rec-

ommendedtooperatethereplace;however,

“AA” batteries can be used for full-time opera-

tion or as a backup in case of a power outage.

Note: Batteries will operate the gas valve

OPEN/CLOSE and pilot ON/OFF functions

only. Electrical power (110 Vac line volt-

age) is required to operate the following

optional components (batteries will not

power any of these options):

GENERAL GAS INFORMATION

AND IMPORTANT NOTICES

• It is critical that a licensed installer

perform these steps strictly per NFPA.

Installing a gas supply line from the fuel

supply to the appliance involves numerous

considerations, including materials, protec-

tion, sizing, location, controls, pressure,

sediment, and more.

• Gas lines must be routed, constructed, and

made of materials that are in strict accord-

ance with local codes and regulations.

Checkwithlocalbuildingofcialsforlocal

code requirements.

• Neverusegalvanizedorplasticpipe.

• A sediment trap (not provided) is recom-

mended in the gas piping within the home to

prevent moisture and debris in the line from

damaging the valve.

• Where required, tightly secure all joints

using appropriate pipe wrenches and seal-

ing compounds.

These appliances must be isolated from

thegassupplypipingsystem(byclosing

their individual manual shutoff 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

shutoff 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).

IMPORTANT NOTICE REGARDING

PROPANE INSTALLATIONS

Propane tanks are at pressures that will

cause damage to valve components.

Verify that the tanks have step-down regu-

lators to reduce pressures to safe levels.

Using a propane tank smaller than

100 lbs may create pressure loss and

insufcient fuel delivery, which can cause

sooting, severe delayed ignition, or other

malfunctions (ref. NPFA 58).

Any damage as a result of insufcient

tank size or other improper installation is

NOT covered under the limited warranty.

• On threaded joints, use a pipe joint com-

pound rated for gas. Always use propane-

resistant compounds in propane applica-

tions. Make sure pipe joint compound

does NOT get inside the pipe.

• It is recommended to seal around the gas

line to prevent cold air leakage.

ATTACHING SECURE VENT™

COMPONENTS

Secure Vent™ direct-vent system components

are unitized concentric pipe components

featuring positive twist-lock connections (see

Figure 13-1).

To attach venting components:

1. Attach the dimpled end of one section to

the incline channel end of the other section,

making sure to align the four dimples with

the inlets of the four incline channels.

2. Push the section being attached against the

adjoining section until fully engaged.

3.Twist the section being attached CLOCK-

WISE, running the dimples down and along

the channels until seated at the ends of the

channels. The sections are properly seated

when the arrow on one section aligns with

the dimple on the other section.

The unitized design of Secure Vent compo-

nents will engage and seal both the inner and

outer pipe without the need for sealant or

screws. If desired, however, a #6 x 1/2" screw

may be used at each joint (not required).

Remember to maintain minimum

clearances to combustibles!

See CLEARANCES section in this manual.

NOTICE: It is important to install

horizontal runs on a steady, (i.e., no

“dips”), slightly positive incline of

approximately 1/4 inch rise-per-foot (20

millimeters rise-per-meter) horizontal,

in a direction away from the replace.

(Slightly smaller rise-per-foot run ratios

are acceptable.) Use a carpenter’s level

to measure from a constant surface, and

adjust support straps as necessary.

FIRESTOP/SPACER

REQUIREMENTS

Vertical Firestop/Spacer must be

used anywhere vent pipe passes

through a combustible oor or

ceiling.

Horizontal Firestop/Spacer must be

used anywhere vent pipe passes

through a combustible wall.

• Use Secure Vent™ Firestop/Spacer with

Secure Vent™ vent pipe.

• Use Secure Flex™ Firestop/Spacer with

restop/spaceronbottomsideofceiling.

•Ifatticspaceisabovetheceiling,install

restop/spacerontopsideofjoist.

2. Route vent sections through the framed

ceiling opening (see Page 9), and secure

restop/spacer with 8d nails (or other

appropriate fasteners) at each corner.

3. Install attic insulation shield (REQUIRED)

to keep insulation materials from touching

vent pipe.

(Attic insulation shield may be used to

obtain required clearances to combus-

tibles. See “Installation Accessories” at

the back of this manual for ordering infor-

mation).

Note: Caulk restops only where pipe

penetrates an outside wall, attic, or other

unconditioned space.

VENT SECTION LENGTHS

(NOMINAL AND EFFECTIVE/NET)

• Plan vent lengths to prevent joints at the

intersection of ceiling or roof joists.

• Ventlengthcombinationsandstraightvent

effective lengths are listed in Figure 14-2.

TELESCOPIC VENT SECTION

A telescopic vent section may be used when

installing in tight spaces or when a vent run that

ismadeupofxed-lengthsectionsdevelopsa

joint in a undesirable location or will not build

up to the required length.

The effective length of the Telescopic Vent

Section ranges from 1-1/2" (38 mm) to 7-1/2"

(191 mm).

The Telescopic Vent Section is tted with a

dimpled end (identical to a normal vent section

component) and a plain end with 3 pilot holes.

Slip the plain end over the locking incline chan-

nel end of a standard vent component the re-

quired distance, and secure with three screws.

ELBOWS

• Whenplanningventruns,makeallowances

for elbows.

• A 90° elbow may NOT be attached directly

to the appliance collar. A minimum of 6"

pipe must be used between the replace

collar and a 90° elbow.

• Two 45° elbows may be used in place of

one 90° elbow (use the same rise-to-run

ratios as shown for a 90° elbow).

• An elbow is acceptable as 1 foot of vertical

rise.

• Each elbow features a 360° swivel joint

(Figure 14-1), which allows it to be rotated

around the center axis of the dimpled end,

to align with the direction of the next vent

run section.

Note: Rotate elbows in a CLOCKWISE

direction only, to avoid unlocking the

previously connected vent section.

LENNOX HEARTH PRODUCTS • RHAPSODY™ LINEAR DIRECT-VENT GAS FIREPLACES (MODEL RHAP54N) • INSTALLATION INSTRUCTIONS

NOTICE: It is important to install

horizontal runs on a steady, (i.e., no

“dips”), slightly positive incline of

approximately 1/4 inch rise-per-foot (20

millimeters rise-per-meter) horizontal,

in a direction away from the replace.

(Slightly smaller rise-per-foot run ratios

are acceptable.) Use a carpenter’s level

to measure from a constant surface, and

adjust support straps as necessary.

Supporting Horizontal Vent Runs

See Figure 15-2. Install support straps every

5 ft (1.524 m) along horizontal/inclined

vent runs using Use Support Straps (cat. no.

SV4.5SU; see “Accessory” section in this

manual) or conventional plumber’s tape (not

provided).

VENT RUN SUPPORT

REQUIREMENTS

Supporting Vertical Vent Runs

Note: Proper venting support is very

important. NEVER use the replace to

support the weight of the venting.

Support the vertical portion of the venting

system every 8 feet (2.4 m) above the re-

place vent outlet (see Figure 15-1).

Use Support Straps (cat. no. SV4.5SU;

see “Accessory” section in this manual) or

conventional plumber’s tape (not provided).

Secure the plumber’s tape to the framing

members with nails or screws. Loop the

plumber’s tape around the vent, securing the

ends of the tape to the framing. Use #6 x

1/2" sheet metal screws to secure the support

straps to the vent pipe.
