t Required filter sizes shown are based on the larger of the ARI (Air Conditioning and Refrigeration Institute) rated cooling airflow or the heating ai_ow velocity of 300

if/minute for throwaway type or 450 ft/minute for high-capacity type. Air filter pressure drop for non-standard filters must not exceed 0.08 in. wg.

install the flue hood as follows:

i. This installation must conform with local building codes and with the National Fuel Gas Code (NFGC), ANSI Z223.1 (in Canada,

CAN/CGA B i49. I, and B 149.2) or NFPA (National Fire Protection Association) latest revision. Refer to Provincial and local plumbing or

wastewater codes and other applicable local codes.

2. Remove flue hood #am shipping location (inside the blower compartment). Place vent cap assembly over flue panel. Orient screw holes

in vent cap with holes in the flue panel.

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

PROCEDURE 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 i/2-in. FPT gas inlet on the

manual shutoff or gas valve.

install a gas supply line that runs to the heating section, Refer to Table 3 and the NFGC for gas pipe sizing. Do not use cast-iron pipe, It is

recommended that a black iron pipe is used. Check the local utility for recommendations concerning existing lines. Size gas supply piping for 0.5

in. wg maximum pressure drop. Never use pipe smaller than the 1/2-in. FPT gas inlet on the unit gas valve.

For natural gas applications, the gas pressure at unit gas connection must not be less than 4.0 in. wg or greater than 13 in. wg while the unit is

operating. For propane applications, the gas pressure must not be less than 7.0 in. wg or greater than 13 in. wg at the unit connection.

An i/8-in. NPT plugged tapping, accessible for test gage connection, must be installed immediately upstream of the gas supply connection to the

gas valve.

When installing the gas supply line, observe local codes pertaining to gas pipe installations. Refer to the NFGC ANSI Z223.1-1988 NFPA latest

edition (in Canada, CAN/CGA B149. I, (2)-M86). in the absence of local building codes, adhere to the following pertinent recommendations:

i. Avoid low spots in long runs of pipe. Grade all pipe I/4 in. in every 15 ft to prevent traps. Grade all horizontal 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 appropriate straps, hangers, etc. Use

a minimum of one hanger every 6 ft. For pipe sizes larger than I/2 in., follow recommendations 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. Never use Teflon tupe.

4. Install sediment trap in riser leading to heating section (See Fig. 9). This drip leg functions as a trap for dirt and condensate.

5. Install an accessible, external, manual main shutoff valve in gas supply pipe within 6 ft of heating section.

6. Install ground-joint union close to heating section between unit manual shutoff and external manual main shut-off valve.

7. Pressure-test all gas piping in accordance with local and national plumbing and gas codes before connecting piping to unit.
