Introduction

This manual is intended for users of air heaters PLANAR-2D-12/24 and PLANAR-

44D-12/24 (hereinafter referred to as heaters). The document covers main rules of

installation of the product on small maritime transport (e.g. yacht, boat, cutter) and function

tests of the product after installation. This manual should be used together with operation

manual of the heater.

1 General instructions and operating principle

The heater can be used only for the purposes specified in the operation manual.

The built-in fan of the air heater draws air through theair intake opening. The air heated

by the heater is channelled to cabins via outlet channels.

Fuel is supplied by a separate fuel pump from the fuel tank of the vessel or from an

additional fuel tank.

The heater is powered by a battery of the vessel.

Temperature in rooms can be regulated by using a temperature sensor and a control

panel, which sets heating parameters.

When a temperature sensor is installed, the heater is constantly comparing the actual

temperature with the set temperature and automatically adjusts the heating capacity

according to the heat demand.

The heater and its components must be installed by specialised

organisations, because the product is complex and consists of a

combustion chamber where fuel is burned, a heat exchanger that supplies

heat resulting from fuel burning, a fuel pump, an air blower, a control unit

controlling the heater according to the programme, etc.

If the heater is handled and/or installed improperly, there is a possibility

of fire hazard, because fuel and electrical components are being used.

That is why all safety precautions must be observed.

2 Safety precautions

2.1 Do not use or install the heater in places, where flammable vapours or gases or large

amounts of dust may form and accumulate.

2.2 Disable the heater, when the vessel is fuelled.

2.3 Disconnect the heater from its battery during repair works on the heater.

2.4 Take the safety precautions, which must be observed when working with an electrical

and fuel systems, when installing and dismantling the heater.

2.5 Do not connect the heater to the power circuit of the vessel, when the engine is

operating and there is no battery.

2.6 Do not disconnect the heater from power before the purge cycle ends.

2.7 Do not connect or disconnect connectors of the heater, when the heater is powered.

2.8 When the heater has been switched off, do not switch it on again for 5-10 seconds.

2.9 Do not step on the heater or put any objects on it and in it.

2.10 Do not cover the heater with clothing, pieces of fabric and so on, and do not place

such objects in front of the air intake pipe or inlet and output of the heated air.

2.11 For safety reasons, contact the service shop to troubleshoot the heater if it fails to

launch two times in a row.

2.12 In case of faults in the operation of the heater, contact specialised repair organisations

authorised by the manufacturer.

2.13 If the consumer fails to follow the requirements above, the warranty of the heater

becomes null and void.

2.14 To ensure reliable operation of the heater, switch it on once a month for 15-30

minutes, including in warm seasons of the year, when the heater is out of operation.

This action is necessary to remove any viscous film sediments on moving parts of the

fuel pump. Failure to do so may lead to premature failure of the heater.

2.15 Fuel in the system has to be changed at least once in a season.

3 Main requirements to installation of assemblies and units of the heater

Install the heater in a dry place that is protected from ingress of overboard water and

condensate, excessive vibrations and heat emissions, engine emissions or fuel or oil

contamination.

The heater must be installed following safety requirements and taking into account the

type of vessel. Consider everything related to peripheral equipment, for example, the

maximum permissible length of the exhaust gas channel, the location of the passage in the

board, air intake for burning, layout and length of electric wires, distance from the fuel tank,

layout of air ducts of warm air, intake of fresh air.

Consider the maximum heel of the vessel. A heel must not bring overboard water into

the discharge channel for exhaust gases, and bilge or overboard water must not get on the

heater.

All precautions should be observed when installing the heater to reduce the risk of

injuries to personnel or damage to the equipment as much as possible.

3.1 Installation of the heater

Install the heater, taking into consideration permissible operating position according

to Fig.1; take into account the possible heel of the vessel. Fig.1 shows two extreme

installation positions of the heater. The distance from surrounding objects must be sufficient

to ensure good ventilation; the distance from walls and partitions to the start of the inlet

opening of the heater must be no less than 50 mm (see Fig.1b). The distance from walls,

partitions to the start of the outlet opening of the heater must be no less than 250 mm.

Provide protection from penetration of foreign objects into intake and output openings,

when installing and operating the heater. Install the heater so that it is convenient to do

maintenance works.

WARNING!!! Reliable operation of the heater depends on correct

installation of the heater. The heater must be installed horizontally

(according to Fig.1).

DO NOT install near flammable or heat-sensitive objects such as

sails, fenders, sheets, paper, gas pipelines, fuel tanks, etc.

When installing the heater, make sure that its casing does not contact the hull of the

vessel (Fig.2). Failure to do so may result in deformation of the heater casing, jamming of

the air blower fan and potential overheating.

It is recommended to use the bracket (can be supplied additionally) (Fig.3) and the

rubber seal for the installation surface of the heater, when installing the heater. Bend the

bracket to the desired position before installation.

3.2 Installation of air ducts.

The air for heating must be taken from clean space without exhaust gases. Never draw

air from the engine compartment.

Fresh air from outside or recirculated air from rooms can be taken for heating.

-Intake of fresh air.

The air is taken from outside, heated and supplied to inner rooms. This operation

renews air in cabins and lowers humidity. Note locations of outlet vents in cabins and make

sure that their number is sufficient. Avoid ingress of overboard or rain water into the inner

space of the heater.

-Air intake from inner rooms.

In this case, heated air is taken from inner rooms. The advantage of such option is fast

heating due to better use of heat. However, this operation does not lower humidity, and the

air in the room is not renewed.

Use only thermally stable air ducts to lay channels for heater air! To avoid

injuries to personnel or damage to the equipment, air channels must have heat

insulation. Heat insulation is also necessary to reduce heat losses, when

laying air ducts in unheated rooms.

Additional air duct components can be added to the heater for distributing hot air. Each

of the components has its own conductivity factor and it reduces total flow rate of hot air.

In order for you to be sure that the option you have selected for the installation of air ducts,

is acceptable and will not result in a massive flow rate reduction of hot air or overheating

of the heater, you need to calculate the total conductivity of complete air duct system (see

example below).

Components connected to heater should

not exceed coefficient of conductivity of

the heater (see Table 1). Otherwise, the

temperature of heated air can increase to

unacceptably high level, heat will be

distributed unevenly, and it could result in

overheating that could damage the heater.

If the sum of individual conductivity coefficients exceeds maximum coefficient of

conductivity of the heater (see Table 1), it can be reduced by increasing the diameter of the

air ducts or installing double channel system instead of a single channel system (Fig.4).

Fig. 4 –Single and double channel air ducts

Single channel system –Only one channel of air ducts connect at heaters air input

(only for PLANAR 2D) and output.

Double channel system –after the heater, the hot air duct splits into two channels. Up

until the point where air duct splits in two channels, it counts as a single channel system,

therefore single channel conductivity coefficients are used for calculations. After that point,

it becomes a double channel system so double channel conductivity coefficients must be

used for calculations.

When using double channel air ducts, at least one channel should

always be open.

See Fig.5 for example of installed air duct. Total conductivity coefficient can be seen

in Table 2. The sum of the individual conductivity coefficients is 44. It does not exceed the

coefficient of conductivity of the heater = 50. In this case, the installation is allowed.

Conductivity coefficients for components of single and double channel systems can

be seen in Table 3.

Fig. 5 –Example of an installed air duct.

The heater is supplied with inlet and outlet grilles already installed. In such a case, the

heater can be used for heating of the room (cabin), in which it is installed. If several cabins

need to be heated, lay air ducts along the perimeter of the vessel. Replace the inlet and/or

outlet grille on the heater to connect the air duct to it (only for PLANAR-44D-12/24 and

PLANAR-2D-12/24). Use a flat screwdriver to disengage hitches on the heater casing and

remove the grille. Install an adapter (only for PLANAR-44D-12/24) and attach the air duct

to it with a clamp. Use different shape adapters and connectors for distribution of warm air

(it is recommended to use Y-shaped adapters to reduce resistance and increase

effectiveness, if possible). Install deflectors on ends of air ducts (Fig.6a for PLANAR 2D,

and Fig.6b for PLANAR 44D).

Do not deform channels with heated air. This may add additional resistance to the flow

of warm air and reduce efficiency of heating.

When distributing supply of hot air, one of deflectors MUST be of a non-closable type

to avoid overheating of the heater.
