MODEL L

TWO-STAGE REGULATOR REPAIR KIT INSTRUCTIONS

Important: Any maintenance, service or repair

should be performed by trained and experi-

enced service technicians. Proper tools and

equipment should be used to prevent injury to

the servicing technician, property or system

components. Service repairs should always be

performed in a safe environment and the tech-

nician should always wear protective clothing

to prevent injury.

The IMPCO PPI-16 repair kit instructions will

provide the technician information to success-

fully repair the Model L regulator. Always in-

spect the major casting pieces for damage,

corrosion or cracks before attempting a service

repair. Be sure the repair kit part number you

are using is correct for the regulator being ser-

viced. Diaphragms are color coded and have

different performance characteristics:

BLACK: Hydrin diaphragm material is the

standard material and is well suited for the

most common applications.

YELLOW: Silicone diaphragm material is the

optional upgrade material that provides excel-

lent flexibility in cold weather climates and is

more resistant to chemical contamination.

Model L Two Stage Converter

Do not use Teflon tape to seal any fuel fittings.

Failure to follow this warning may cause the

regulator to leak internally, possibly resulting in

serious injury and/or property damage and may

void any warranty coverage.

REBUILD INSTRUCTIONS

1. Model L Repair Kit (RK-L) contains all nec-

essary parts to replace components subject

to deterioration (see page 2 for repair kit

components). Installation of repair kit should

be necessary only at the time of a major

overhaul or when converter has been out of

service for a significant length of time.

Note: Gaskets and diaphragms deteriorate if

converter is stored after use.

2. Inspect repair kit component parts to ensure

the kit is complete. Start disassembly by

removing the eight screws (2) securing sec-

ondary cover assembly (3).

3. Tap cover (3) loose with plastic screwdriver

handle and remove secondary diaphragm

assembly (5). The diaphragm assembly

must be moved away from water inlet-outlet

to disengage diaphragm link from the lever

assembly. Discard diaphragm assembly.

4. Early Models Only For later models, skip to

step 7. Loosen screw (10) which retains ful-

crum pin (8).

5. Remove screw (10).

6. Slide fulcrum pin (8) to side as shown to

release lever assembly (6 & 7). In some

cases, the pin may come out entirely.

Retain it for reassembly steps. Skip to

Step 8.

7. Later Models Only For early models,

skip to Step 8. Remove two screws (28)

with T-20 Torx tool to release the fulcrum

pin (8).

8. Remove secondary lever and seat as-

sembly (6 & 7) and secondary regulator

spring (9). Retain pin and spring; discard

lever and seat.

9. Remove remaining screws (10) securing

primary diaphragm cover (11) and re-

move the cover.

10. Removal of primary diaphragm cover

(11) frees two primary springs (12) and

primary diaphragm assembly (13). Re-

11. Remove primary diaphragm assembly

(13). Slide the diaphragm assembly to

disengage slot from primary valve pin

(20). Discard primary diaphragm as-

sembly. Pencil tip points out pin.

Note: Primary valve is actuated by this

pin through the body. This isolates the

diaphragm from any contact with liquid

propane.

12. Turn over and loosen fuel inlet bushing

(27) using a tube wrench or six sided

socket.
