2. Safety Instructions
WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause injury or property damage. Read the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment.
- Ventilation is Crucial: This heater is designed for use in well-ventilated indoor spaces only. Never use this heater in unventilated areas, bedrooms, or sleeping areas. Ensure adequate fresh air supply to prevent carbon monoxide accumulation.
- Gas Type: Use only propane and/or butane gas cylinders up to 13 kg. Ensure the gas regulator and hose are compatible with your local gas supply standards. The included hose and regulator are standard for DE, AT, CH, and SK. For other countries, appropriate accessories may be required.
- Safety Features: The heater is equipped with an integrated Oxygen Depletion Sensor (ODS), a pressure reducer, tilt protection, and overheat protection. Do not bypass or modify these safety features.
- Clearance: Maintain a safe distance from flammable materials (curtains, furniture, paper, etc.). Do not place objects on or near the heater.
- Stability: Ensure the heater is placed on a stable, level surface. The integrated wheels are for mobility, not for operation on uneven ground.
- Children and Pets: Keep children and pets away from the heater during operation and while it is cooling down. The safety grid protects against direct contact with the ceramic plates, but surfaces can still be hot.
- Storage: Store gas cylinders in a well-ventilated area, away from heat sources and direct sunlight. Disconnect the gas cylinder when the heater is not in use for extended periods.
- Maintenance: Only perform maintenance as described in this manual. For complex repairs, contact qualified service personnel.

- 1x MONZANA GH4500 Gas Heater
- 1x Gas hose (50 cm)
- 1x Gas pressure regulator (50 mbar)
4. Setup
Follow these steps to set up your gas heater:
- Unpack: Carefully remove all packaging materials and inspect the heater for any damage.
- Positioning: Place the heater on a firm, level surface in a well-ventilated indoor area. Ensure adequate clearance from walls and flammable objects.
- Gas Cylinder Installation: Open the rear compartment of the heater. Place a gas cylinder (up to 13 kg, propane/butane) inside the designated area.
- Connect Regulator and Hose: Attach the gas pressure regulator to the gas cylinder valve. Then, connect the 50 cm gas hose to the regulator and the heater's gas inlet. Ensure all connections are tight and secure.
- Leak Test: Before first use and after every gas cylinder change, perform a leak test using soapy water. Apply soapy water to all gas connections. If bubbles appear, there is a leak. Tighten connections or replace faulty parts. Never use an open flame to check for leaks.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your heater:
- Cleaning: Ensure the heater is completely cool before cleaning. Wipe the exterior surfaces with a damp cloth. Do not use abrasive cleaners or solvents. The ceramic plates can be gently wiped with a damp cloth.
- Inspection: Periodically check the gas hose and connections for signs of wear, cracks, or damage. Replace any damaged components immediately.
- Storage: When not in use for extended periods, disconnect the gas cylinder and store the heater in a dry, dust-free location. The heater's robust construction and coated surface are designed for durability.
7. Troubleshooting
If you encounter issues with your heater, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not ignite. | Gas cylinder empty or valve closed. Gas connections loose. Ignition electrode dirty or faulty. | Check gas cylinder level and open valve. Tighten all gas connections and perform leak test. Contact service for inspection. |
| Flame goes out during operation. | Insufficient ventilation (ODS activated). Gas cylinder running low. Tilt protection activated. | Ensure adequate ventilation. Move to a more ventilated area. Replace gas cylinder. Ensure heater is on a stable, level surface. |
| Smell of gas. | Gas leak. | Immediately turn off gas supply at the cylinder. Ventilate the area. Perform a leak test. Do not operate the heater until the leak is resolved. |
