General Instructions

GENERAL INSTRUCTIONS

This installation guide provides you with easy to follow illustra­tions and instructions to assemble your MHP Gas Barbecue
Grill.

Before you start assembling and using your MHP Gas Bar­becue Grill we recommend that you read through all pre­cautions, safe guards and instructions to avoid any per­sonal injury or property damage.

Check Local Codes. Contact your local LP dealer or Natural

Gas company for recommended installation procedures and
regulations. If there are no local codes, installation must con­form to the latest National Fuel Gas Code: ANSI Z 223.1. For
Canada, installation must comply with local codes and/or
Standard CAN/CGA-B-149-1 for natural gas installation and
CAN/CGA- B-149-2 for propane installation.

For LP Gas Models the supplied Type 698 (HR4B) Regulator
must be used. Any replacement pressure regulator or hose
assembly must meet or exceed the specifications of the HR4B
Regulator.

Only Worthington, Manchester, or Wolfdale brand cylinders
should be used with this appliance.

For Natural Gas Models the grill is designed to operate at a

pressure of 7” water column (W.C.) (1.75 kPa). Check your gas
utility for local pressure. Pressures other than approximately 7”

W.C. could affect the performance of your grill.

ASSEMBLY INSTRUCTIONS

There are 9 steps to assembling your MHP Gas Barbecue Grill:
The mounting, LP tank mounting, control panel, gas supply
connection, grill lid, lid handle, side shelves, and rock grate,
cooking grid and warming rack.

The grill itself is partially assembled with the Burner, Venturis,
Ignitor Collector Box and the Gaslow Regulator installed.

The JNR, WNK and TJK grills are specifically designed to fit
the five mounting methods: Cart, In-Ground Post, Deck/Patio
Base, Column and Built-in.

You will need the following tools to assemble your grill:

 A Phillips head screwdriver

 A standard flat head screwdriver

 Two 7/16” wrenches or sockets

STORAGE

Turn gas OFF at the LP cylinder (or at the shut OFF valve in
the case of Natural Gas) when the MHP Gas Barbecue Grill is
not in use.

Do not store spare LP cylinders under the MHP Gas Barbecue

OPERATING SAFEGUARDS

Do not install your MHP Gas Barbecue Grill in or on

recreational vehicles and/or boats.

Never use your MHP Gas Barbecue Grill near combus-

tible surfaces, including roof overhangs, roofs, vinyl
siding and window shutters.

Use this barbecue outdoors in a well-ventilated area.

Do not use your MHP Gas Barbecue Grill in a shed, gar-

age, building, breezeway or any other confined area.

Do not use any kind of combustible material on or near

the top, bottom, back or sides of the grill. Maintain at
least an 18 inch clearance.

Leak test all gas supply line connections.

Do not let children operate a gas grill.

Keep the area around the grill clear of combustible va-

pors or liquids such as gasoline.

When operating the grill do not leave unattended. Keep

children and pets away.

Keep fuel supply hose and electrical supply cord away

from any heated surface.

YOUR GRILL IS DESIGNED FOR OUTDOOR USE ONLY.

It should also not be used in an enclosed area such as a shed or garage
because combustion uses available oxygen and discharges carbon mon­oxide.
The grill must be located no closer than 18" from any combustible surface
behind or to the sides. Grill should not be located under overhead unpro­tected combustible surfaces.
Keep the area around the grill clear of combustible materials, flammable
vapors or liquids such as gasoline.
Do not obstruct the flow of combustion and ventilation air.

Deck/Patio Base

1. Mark the location of the four holes at the outside corners of the
patio base and drill four holes. The base will be fastened down
with lag bolts (not supplied by MHP) after you have connected
the gas supply line. The top post notch is the front and the rear
access door will be in the back of the grill.

2. Run the gas supply line into the post from the bottom to reach
the access door and bend it 90° to exit the base at either notch.
The patio base is notched on two sides to allow the gas line to
exit either right or left.

3. Secure the gas line with the tube clip. (Option: On a raised deck
if the gas supply line is to be run straight up into the post from
below use the tube clip to attach the gas line to the deck for
support.

4. At the access door connect a 3/8" flare coupling (not supplied by
MHP) to the gas supply line and Stainless Steel tubing. Position
the tubing in the top notch of the post. Bend the tubing at the top
end to match the Feed Line of the grill valve. Do not kink the

tubing.

TUBE BENDING: For proper bending of the stainless steel tubing, see

page 26 for bending instructions.

Step 1: Deck/Patio Base Mounting Assembly (Fig. 5)

1. Turn base on edge and insert the 2’ post. Align the notches in

the post with the notches in the base. IMPORTANT: Close
tolerances may require you to tap the top of the post to seat it
completely in the base socket which will then align the bolt
slots.

2. Fasten post to base with four ¼ - 20 x ¾" Hex bolts, washers
and Kep nuts. Follow exact placement of washers as indicat­ed. Tighten securely.

3. Attach the tube clip with the 8 - 32 self-tapping screw either on
the right or left side of the base depending on the direction of
your gas supply line.

Step 3: Attaching The Grill Head Bottom To The Deck/

Patio Post (Fig. 7 & Fig. 8)

1. To make the post-to-flange connection easier, remove the grill
burner by taking out the small clip located under the bottom grill
head. This will allow access to hold the Kep nuts inside the
post.

2. Set the grill head bottom carefully in place, align holes and use
the ¼ - 20 x ¾" bolts and ¼-20 Kep nuts to attach the grill
flange to the post.

Step 2: Deck/Patio Mounting Installation

Step 1: In-Ground Mounting Installation (Fig. 9)

1. Dig a posthole about 8 inches wide by 2 feet deep. Cau-

tion: Locate the hole so that the mounted grill head has
a clearance of 18 inches away from any combustible
object or surface; back, left or right.

Center the post in the hole and plumb it. Pour in cement
(gravel) up to the gas line access hole.

Keep in mind that the gas line access hole is on
the back of the post and the notch at the top if facing front.

Recheck plumb and allow cement to set.

2. Run the gas supply line into the post access hole (just above
the cement). Make a 90° bend to reach the access door
opening.
The gas supply line should be trenched at least 18
inches below the surface of the ground to prevent damage
from digging. CAUTION: The gas supply line must be reg-

ulated (in the case of natural gas that means connected
after your gas meter and regulator) and that you have an
easily accessible shut-off valve.

3. At the access door connect a 3/8" flare coupling (not supplied
by MHP) to the gas supply line and Stainless Steel tubing.
Position the tubing in the top notch of the post. Bend the
