3. Function
The heater is a hot water and warm air integrated machine,
which can provide domestic hot water while heating the
occupants. This heater allows use during driving. This
heater also has the function of using local electricity
heating.
In hot water warm air work mode, this heater can be
used to heat both the room and the hot water. If only hot
water is needed, please choose hot water working
mode.
When the ambient temperature is below 3°C, please
empty the water in the water tank to prevent freezing
of the water tank.
There are three energy options to choose from:
-- Diesel Mode
Heater automatic adjust the power。
--Electrical Mode
Manually select the 900W or 1800W heating mode
according to the power supply capacity of the RV camp.
--Mixed Mode
When the power demand is low (for example, maintaining
the room temperature stage), the electrical mode is
preferred. Diesel Mode is not initiated until the mains
supply is not met, and the diesel mode function is turned
off first during the power adjustment phase.
In hot water working mode，diesel mode or electrical
mode is used to heat the tank。The tank temperature can
be set to 40°C or 60°C.
-- Diesel Mode
The heater operates at the lowest power. Stop heating
immediately after reaching the set temperature.
--Electrical Mode
Manually select the 900W or 1800W heating mode
according to the power supply capacity of the camp site.
4. Safety Instructions

The heater installation location should be selected from
load-bearing floor, double floor or underfloor.
If there is no suitable floor, you can first make a load
bearing surface with plywood.
★The heater must be firmly fixed to the mounting surface
with screws to prevent damage to the diesel pipeline
during
and cause danger.
Depending on the actual installation, may only install three
screws. Two die-cast aluminum fixing screws are fixed
then choose a plastic right angle to fix it.
To ensure that the heater evenly distributes heat, the
heater should be installed in the center as much as
possible to ensure that the heating circuit is equal long as
possible.
No cover is allowed to add to the heater surface.
The size with* is the smallest size, leaving enough space
to connect accessories such as diesel and water pipes.

To prevent the danger from heater accidentally
loosening, the upper cover of the heater compartment is
screwed to the upper cover (Figure 4-1). Next to the
installation location it is necessary to install a strong
partition strip in front of the heater, perpendicular to the
direction of travel. Above the floor height180mm can be
attached to a septum (minimum 30*50mm).
Heat sensitive objects and flammable objects should be
placed away from the heater.
★ The exhaust cowl must be on the side wall or
ceiling.
In the exhaust cowl installed area， there is no
ventilation window in the range of 300mm, and there is
no refueling port or tank respirator in the range of
500mm.
The exhaust cowl is mounted below the window that is
close to or operable. A window switch should be installed
to ensure that the heater is turned off automatically when
the window is opened.
Air Inlet Hose and exhaust hose Installation
The exhaust pipe is pass through the intake pipe.
The length of the intake and exhaust pipe is as shown in
Fig. 6, and the shortest is 60cm and the longest is
100cm. The exhaust cowl is only allowed under the
exhaust outlet 20cm.
After the intake and exhaust pipes are pierced from the
through holes, they must be cut short, and the exhaust
pipes are slightly shorter than the intake pipes. Avoid
excessive expansion or tension on the exhaust pipe.
The length of the intake and exhaust pipes is 100 cm to
200 cm, as shown in Figure 7. The piping must be
arranged in the ascending direction。

Select a flat mounting surface so that combustion air can
enter from all sides. Drill one hole of φ83. Seal (Fig. 8-8),
with the plane facing the exhaust cowl. Wear the fixing
clip before installing the exhaust pipe (Figure 8-3). Pay
attention to the installation of the smoke cap upwards。
20mm at the end of the exhaust pipe should be
compressed, do not straighten. Insert the exhaust pipe
into the exhaust cowl interface（Figure 8-10），as deep
as possible. Try to fix the clips on the top, tighten.
Place the air intake pipe (Figure 8-2) over the exhaust
cowl tooth (Figure 8-11). Set on the fixed clip（Figure8-
7）, tighten. Secure the exhaust cowl with 6 screws
(Figure 8-9). Use 2 screws to fix the exhaust cowl.
Fix the exhaust pipe on the side wall with mounting clip
（Figure8-7）.
Connect Air Inlet and exhaust pipe to The Heater
20mm at the end of the exhaust pipe (Figure 9-1)should
be compressed, do not straighten.
Try to insert the exhaust pipe on exhaust port (Figure 9-
2)as deep as possible. fix the clip on top, tighten.
Place the air intake pipe (Figure 9-3) over the air inlet
port (Figure 9-5). Set on the fixed clip (Figure9-6）,
tighten.
Warm Air Intake
The warm air intake is drawn in by the heater. There
must be a total area between the room and the heater
not less than 150cm2 opening.
Ensure that the warm air intake is not contaminated by
the engine or heater exhaust, if necessary, with
structural isolation measures.
Figure 10

Warm Air Distribution
Most of the warm air is imported into the floor area of the
living compartment through the bellows.
The four air outlets on the heater are connected to the
φ65 bellows. Use only pressure piping that meets the
quality requirements of the JP. Other pipes that do not
meet our quality standards (especially wind resistance,
pipe diameter and number of ripples) shall not be used.
If the warm air duct must withstand a considerable
amount of bending immediately after the hot air outlet of
the heater in a limited space, we recommend using a 90°
elbow (Figure 3-37). This elbow can be connected to a
diameter of mm hot air duct.
In the case where the length of the pipe is less than 2
meters, the air outlet cannot be installed at a height
higher than the connection of the warm air duct. When
the pipe length is less than 50cm, the pipe must be
siphon between the connector and the outlet. These
measures prevent the undesirable heating caused by
(fairing effect) convection of the vehicle during summer
operation.
★The warm air pipe must be firmly inserted into the
connection port.
★To get the best warm air distribution, JP recommends
using 4 warm air outlets for the heater.
★ The cross section of the heater duct must not be
reduced due to pipe connections or the analogue. That is
to say, the number of warm air duct outlets (Fig. 3_32) is
not less than four, ensuring that more than four warm air
outlets are open.
Diesel System Connection
Figure 12
Figure 11

JP Heater

The fuel is taken from the fuel tank of the vehicle or
supplied from a special 10L fuel tank. The fuel pump and
fuel supply are adjusted by a special oil pump (provided
by the manufacturer). It is not allowed to extract fuel from
the return system of the vehicle engine or downstream of
the vehicle internal transfer pump.
Use only fuel hoses and tubing within the scope of
delivery for installation.
Fuel should meet national standards. GB19147-2013
Vehicle Diesel Standard.
Winter fuel should be used in accordance with low
temperature requirements, not allowed to use bio-
fuels.
Diesel Fuel Lines System
Oil pipeline installation
The tubing must use the kit's accessories, which are
nylon hoses that are resistant to light and heat. Allowable
fuel line length: The maximum fuel line length on the inlet
side is 2 meters and the pressure side is max 6 meters.
As Figure 13 shows.
Safety regulations for fuel lines
Always use a hose cutter or sharp tool to cut the fuel
hose and tubing to length. The area being cut cannot be
compressed and must be free of burrs. The fuel lines
must be securely connected to prevent damage and/or
noise due to vibration (the recommended distance
between the joints is approximately 50 cm). Fuel piping
must be protected from mechanical damage. The laying
of the fuel line will not adversely affect the stability of the
vehicle, engine operation and the like. Protect fuel-laden
components from high temperatures that may affect
operation (use a suitable fiberglass-lined aluminum heat
protection hose). Never set or secure fuel lines near the
exhaust pipe of the heater or vehicle engine.
Figure 13

JP Heater
12
If the lines are crossed, keep a sufficient distance from
the hot parts - if necessary, provide a thermal radiation
shield. The tubing installation should be able to prevent
flying stones from hitting and away from the heating
parts of the vehicle. If necessary, install protective
devices.
Fuel Pump Installation
The oil pump should be fixed with the oil pump fixing
ferrule (rubber). The oil pump outlet should be tilted
upwards and its installation angle should be selected
from 15° to 35° (Figure 14). When conditions permit, the
tubing from the oil pump to the heater mainframe should
gradually rise. To prevent the oil pump from being
exposed to heat (maximum operating temperature)
40 ° C), so do not install near the exhaust pipe.
The difference in height between the fuel level and the
oil pump and the height difference between the oil pump
and the main engine inlet will create pressure (or
suction) in the oil circuit, so these dimensions should
meet the requirements of Figure 14.
Heater and fuel pump connection
The direction of the tubing from the fuel pump to the
heater should be as far as possible. A hole for passing
through the fuel line and the fuel pump connection cable
is marked at a suitable location on the vehicle floor.
Before drilling, be sure to check the hidden cables, fuel
pipes, frame sections, etc.! Then use the under-body

JP Heater
13
protection to seal the edges of the openings in the
vehicle floor. To prevent the tubing and oil pump cable
from being broken, add a bushing or cross-section edge
protection material.
The tubing should be bundled and secured at a suitable
location with a bundling distance of no more than 50 cm.
The connection between the oil pipe and the oil pump,
the main engine, and the fuel tank (the nozzle) should be
made with the oil pipe joint of the machine and clamped
with the oil pipe clamp. Prevent bubbles from forming at
the joint (Figure 15).
Fuel Filter Installation
Install the fuel filter in front of the fuel inlet of the fuel
pump. When installing, be aware that the fuel filter must
be vertically up (to ensure that the impurities are
deposited downward).
The fuel filter replacement cycle is two years, and the
tubing joints and clamps must be replaced at the same
time.
Installation of the nozzle (Fig. 17)
Put the nozzle on the O-ring first, and then pass it out
from the inside of the tank through the bottom φ8 hole
(can be processed by itself). Put a washer on the outside
of the tank and tighten with a nut. The tightening torque
is 6Nm+1Nm.
The O-ring must be sandwiched between the inner side
wall of the tank and the nozzle to ensure a good seal
between the nozzle and the tank. (The accessories such
as the nozzle are included in the fuel tank)
Figure 15
Figure 16

Fuel Suction pipe installation (Figure 18)
Use when drawing fuel from the vehicle's own fuel tank.
When installing, please pay attention to the installation
hole size on the fuel tank (or fuel tank cap) is φ25±0.2,
the edges are neat, and the circumference is flat to
ensure a good seal with the suction pipe socket. The
distance between the lower mouth of the suction pipe
and the bottom of the fuel tank should be 30-40mm,
which can ensure the full absorption of fuel and prevent
the inhalation of impurities deposited at the bottom of the
tank.
Water pipe connection
Water can be supplied to the tank using a pressure
pump or immersion pump with a pressure of 2.8 bar.
If the tank is connected to a centralized supply (rural or
urban connection), or if a high pressure pump is used, a
pressure reducer must be used, which will prevent
pressures above 2.8 bar.
★ The temperature rise and expansion of the water
before the relief valve is triggered may result in
pressures up to 4.5 bar (may also occur with the
immersion pump). The water pipes connected to the
water tank and the safety/drainage valve must be water
pipes that are safe for drinking water, pressure resistant
(up to 4.5 bar) and heat resistant water up to 80 °C.
Antifreeze valve (Figure 3-39, antifreeze automatic
drainer), a mechanical safety/drain valve. When there is
a danger of frost, it will automatically drain the water
from the tank through the drain.
A pressure relief valve must be installed (Figure 3-41,
0.5 MPa). If there is excessive pressure in the system,
the pressure will automatically be released intermittently
through the pressure relief valve.
External temperature sensor installation
Install the car and measure the room temperature. The
sensor installation location is determined by the RV
manufacturer based on the specific conditions of the
vehicle. When selecting the installation location, please
note that the external temperature sensor should not be
exposed to direct heat radiation.
Figure 17
Figure 18

JP Heater
15
For optimum room temperature control, install an
external temperature sensor above the entrance door
Make sure the external temperature sensor is always
installed on the vertical wall. There must be free flowing
air around it.
Drill a hole with a diameter of 10mm. The single-wire
terminal passes through the opening from the back and
connects the end of the cable to the sensor with an
insulated connector plug (no polarity is required). Sliding
into the outside temperature
Sensor and connect the two ends of the cable to the two
insulation connectors to the heater electronics (if
necessary, extend the cable to a maximum length of 10
meters, 2 x 0.5mm2
cable).
The external temperature sensor provided must always
be connected or the heater will switch to fault.
LCD Control Switch Installation
The gas heater must be operated with a dedicated LCD
switch. See the relevant instructions for details.
Electrical Connection
Lay the wires to avoid scratches. If there is a sharp
edge, if the metal panel is threaded, use a lead bushing
or edge protection accessory.
The connector cable must not be attached or in contact
with metal surfaces, exhaust pipes or hot air ducts.
The electrical connector is located below the controller
cover. The controller cover can be removed by pressing
and simultaneously sliding in the direction of the arrow.
When removing or installing the controller cover,
make sure that the connecting cable is not pulled
out or squeezed.

All cables connected to the heater must be hung in the
direction of sagging. This will prevent condensate water
slipping off from the connector cable and into the heater.
The connector cable and plug must be free of force.
Bundling connector cable (See Figure 23), attach it to
the housing with a cable tie to eliminate tension.
All cables must be securely connected and must not be
loose or disconnected due to vibrations, causing a fire
hazard!
