Untrained personnel can perform basic maintenance flmc- tions of cleaning coils and filters. All other operations should be performed by trained service personnel. When working on

air conditioning equipment, observe precautions in the lit erature, tags and labels attached to the unit, and other safety

precautions that may apply. Follow all safety codes. Wear safety glasses and work gloves.

Use quenching cloth for unbrazing operations. Have fire ex- tinguisher available for all brazing operations.

NOTE TO INSTALLER -- Before the installation, READ

THESE INSTRUCTIONS CAREFULLY AND COMPLETELY.

Also, make sure the User's Manual and Replacement Guide are left with tile unit after installation. The furnace is NOT

to be used for temporary heating of buildings or structures under constrttction.

SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical compo

nents. Only trained and qualified personnel should install, repair, or service air conditioning equipment.

I. GENERAL

The PY1P units (see Fig. 1) are fidly self-contained, combi- nation Category I gas heating/electric cooling units designed

for outdoor installation. See Fig. 2 5 (pages 2 5) for unit di- mensions. All unit sizes have discharge openings for both hori

zontal and downflow configurations, and are factory shipped with all 4 duct openings covered. Units may be installed ei-

ther on a rooftop or a groundqevel cement slab. See Fig. 6 for roof curb dimensions.

RECEIVING AND INSTALLATION

I. STEP 1 -- CHECK EQUIPMENT

A. Identify Unit

The unit model nmnber and serial number are stamped on unit identification plate. Check this information against ship

ping papers and job data.

B. Inspect Shipment

Inspect for" shipping damage while unit is still on shipping pallet. If unit appears to be damaged or is torn loose fl'om its

anchorage, have it examined by transportation inspectors be- fore removal. Fm_vard claim papers directly to transporta-

tion company. Manufacturer is not responsible for any darn age incnrred in transit.

Check all items against shipping list. hnmediately notify your representative if any item is missing.

To prevent loss or damage, leave all parts in original pack ages until installation.

II. STEP 2 -- PROVIDE UNIT SUPPORT

A. Roof Curb

Install accessory roof curb in accordance with instructions shipped with curb. See Fig. 6 for roof curb dimensions. In

stall insulation, cant strips, roofing, attd flashing. Ductwork must be attached to curb.

IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasketing material sup-

plied with the roof curb. hnproperly applied gasketing can also result in air leaks and poor" unit performance.

Curb should be level to within 1/4inch. This is necessa W for unit drain to flmction properly. Refer to accessory roof curb

installation instructions for additional information as required.

B. Slab Mount

Place the unit on a solid, level concrete pad that is a mini mmn of 4 in. thick with 2 in. above grade. The slab should be flush on the front of the unit (to allow condensate drain in-

stallation) and should extend 2 in. on the three remaining sides of the unit. See Fig. 7. Install a 6tin. gravel apron in

fl'ont of condenser air inlets to prevent obstrtiction of airflow by grass or shrubs. Do not secure the unit to the slab exc'u_t

when required by local codes.

C. Flush Mount

Place side of unit with duct panel flush against transition. On units with optional base rails, the skirt on duct-panel side of unit cat] be removed or relocated to allow unit to be mounted

flush against transitions that extend below basepan of trait, To move skirt, proceed as follows:

1. Remove 4 screws holding skirt to base rail. Retain screws.

2. Remove skirt or slide skirt inwards until alternate clear ance holes align with base rails.

3. Secure with screws removed in Step 1. Holes align with base rails.

To remove wood support under unit (with base rail only), loosen 4 screws above rigging holes and slide assembly out through

rectangular hole.

III. STEP 3 -- FIELD FABRICATE DUCTWORK

Secure all ducts to roof curb and building structure on verti- cal discharge units. Do [rot cczmect chlctwork to unit. For hori-

zontal applications, unit is provided with flanges on the hori zontal openings. All ductwork should be secured to the flanges.

Insulate attd weatherproof all external ductwork, joints, attd roof openings with counter flashing and inastic in accordance with applicable codes.

Ducts passing through an unconditioned space must be in- sulated and covered with a vapor barrier.

If a plenmn return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes.

A minimum clearance is not required around ductwork. Cabi- net return air static shall not exceed -.25 in. wg.

IV. STEP 4 -- PROVIDE CLEARANCES

The required n_inimunt operating and service clearances are shown in Fig. 2-5. Adequate combustion, ventilation, and cot]-

denser air must be provided, in accordance with section 5.3, Air for Combustion and Ventilation, of the National Fuel Gas Code ANSI (American National Standards Association) Z223.1

(in Canada, sections 7.2, 7.3 or 7.4 or Can/CGA [Canadian

Gas Association] B 149 Installation Codes), or applicable pro- visions of local building code.

The condenser fat] pushes air through the condenser coil and discharges it through the bank of louvers in the top cover,

the decorative grille on the right side of the unit, and the con> presser access panel. Be sure that the fan discharge does not

recirculate to the condenser coil. Do not locate the unit in ei- ther a corner or tinder an overhead obstruction. The mini-

mum clearance under a partial overhang (such as a normal house overhang) is 48-in. above the unit top. The maximunl

horizontal extension of a partial overhang must not exceed 48 inches.

Do not place the unit where water, ice, or snow fl'om an over- hang or roof will damage or flood the unit. Do not install the

unit on carpeting, tile, or other combustible materials. The unit may be installed on wood flooring or on Class A, B, or C

roof covering materials.

V. STEP 5 -- RIG AND PLACE UNIT

Use spreader bars or crate top when rigging the unit. The units must be rigged for lifting as shown in Fig. 8 and 9. Re-

fer to Table 1 for operating weight attd to Fig. 2 5 for" corner weights. U[se extreme c'ozlticzr to pz'eveirt ct_moge wheir mov

Fig. 9 -- Suggested Rigging for Units With

Optional Base Rail

A. Units Without Base Rail

If accessory rigging brackets are to be used for rigging, in- stall them as follows:

1. Position brackets as close to the corners of unit as pos- sible. Be sure brackets are well outside of center of grav-

ity. See Fig. 2 and 4.

2. Position paint protectors and foam strips between screws and painted surface of unit. Tighten screws until they

make contact with the paint protectors.

3. Secure device or hook of sufficient strength to hole in bracket as shown in detail "A" of Fig. 8.

4. If wood top is available, use it for a spreader bar to pre-

vent straps fl'om damaging unit. If wood top is not avail-

able, use spreader bars of sufficient length.

--8--

B. Units With Optional Base Rail

Lifting holes are provided in optional base rail as shown in Fig. 9. Operating weights are shown in Table 1. Refer to rig-

ging instructions on unit. Protective wood support must be removed from unit before

unit is mounted to curb. Remove 4 screws that secure sup port above rigging holes in rails. Slide support out through

rectangular hole in rail. See Fig. 9.

Vl. STEP 6 -- CONNECT CONDENSATE DRAIN

NOTE: When installing condensate drain connection be sure to comply with local codes and restrictions.

Model PY1P disposes of condensate water through a 3/4 in. NPT fitting which exits through the compressor access panel.

See Fig. 2 5 for location. Condensate water can be drained directly onto the roof in roof

top installations (where permitted) or onto a gravel apron in groundqevel installations. Install a field-supplied conden-

sate trap at end of condensate connection to ensure proper drainage. Make sure that the outlet of the trap is at least

1 in. lower than the drain pan condensate connection to pre

vent the pan fi'om overflowing. See Fig. 10. Prime the trap with water. When using a gravel apron, make sure it slopes

away fl'om the unit. If the installation requires draining the condensate water away

fi'om the unit, install a 2-in. trap at the condensate connec- tion to ensure proper drainage. See Fig. 10. Make sure that

the outlet of the trap is at least 1 in. lower than the drain- pan condensate connection to prevent the pax] fi'om overflow

ing. Prime the trap with water. Connect a drain tube using a minimum of 3/4 in. PVC or 3/4 in. copper pipe (all field

supplied) at the outlet end of the 2-in. trap. Do not undersize the tube. Pitch the drain tube downward at a slope of at least

one in. for every 10 ft of horizontal run. Be sure to check the drain tube for leaks.

1" MIN,

Fig. 10 -- Condensate Trap

VIII, STEP 7 -- Install Flue Hood The flue hood assembly is shipped screwed to the control box

in the burner compartment. Remove the burner access panel to locate the assembly.

Fox" units being installed in California Air Quality Manage ment Districts which require NO x emissions of 40 nanograms/

joule or less, kit CRLOWNOX001A00 must be installed.

Install the flue hood as follows:

1. This installation must conform with local building codes and with the National Fuel Gas Code (NFGC), ANSI Z223.1 (in Canada, CAN/CGA B149.1, and B149.2), or

NFPA (National Fire Protection Association) latest re vision. Refer to Provincial and local plumbing or waste-

water codes and other" applicable local codes.

2. Remove fl'om shipping location. Place vent cap assem bly over fine panel. Orient screw holes in vent cap with

holes in the fine panel.

3. Secure flue hood to flue panel by inserting a single screw on the right side, the left side, and the top of the hood.

VIII. STEP 8 -- INSTALL GAS PIPING

The gas supply pipe enters the unit through the access hole provided. The gas connection to the unit is made to the 1/d in.

FPT gas inlet on the manual shutoff or gas valve. Install a gas supply line that runs to the heating section. Re

fer to Table 2 and the NFGC for" gas pipe sizing. Do not zl.se ca.st iron pipe. It is recommended that a black iron pipe is

used. Check the local utility fox" recommendations concern- ing existing lines. Size gas supply piping fox" 0.5 in. wg maxi-

mum pressure drop. Never" zLse pipe _smaller than tire _/z-hr. FPT go_s hrlet on tire unit ga_s valve.

For natural gas applications, the gas pressure at unit gas cox]- nection must not be less than 4.0 in. wg or greater than

13 in. wg while the unit is operating. For propane applica-

tions, the gas pressure must not be less than 4.0 in. wg or greater than 13 in. wg at the unit connection.

An l/a-in. NPT plugged tapping accessible for test gage cox]- nection must be installed immediately upstream of the gas

supply connection to the furnace. When installing the gas supply line, observe local codes per

raining to gas pipe installations. Refer to the NFGC ANSI Z223.1-1988 NFPA latest edition (in Canada, CAN/CGA B 149.1,

(2) M86). In the absence of local building codes, adhere to the

following pertinent recommendations:

1. Avoid low spots in long runs of pipe. Grade all pipe V4 inch in every 15 ft to prevent traps. Grade all hori-

zontal runs downward to risers. Use risers to connect to

heating section and to meter.

2. Protect all segments of piping system against physical and thermal damage. Support all piping with appropri-

ate straps, hangers, etc. Use a minimum of one hanger every 6 ft. Fox" pipe sizes larger than _?z in., follow rec

ommendations of national codes.

3. Apply joint compound (pipe dope) sparingly and only to

male threads of joint when making pipe connections. Use

only pipe dope that is resistant to action of liquefied petroleum gases as specified by local and/or national codes.

Newt u_se Teflon talre.

4. Install sediment trap in riser" leading to heating section per Fig. 11. This drip leg functions as a trap for" dirt and

condensate.

5. Install an accessible, external, manual main shutoffvalve

in gas supply pipe within 6 ft of heating section.

6. Install groundOoint union close to heating section be- tween unit manual shutoff and external manual main

shutoff valve.

7. Pressure test all gas piping in accordance with local and

national plumbing and gas codes before connecting pip- ing to unit.

NOTE: Pressure test the gas supply system a/terthe gas sup- ply piping is connected to the gas valve. The supply piping

must be disconnected from the gas valve during the testing of the piping systems when test pressure is in excess of

0.5 psig. Pressure test the gas supply piping system at pres- sures equal to or less than 0.5 psig. The unit heating section

must be isolated from the gas piping system by closing the external main manual shutoff valve and slightly opening the

groundOoint union.
