Installation instructions

3.3.2Condensate drain requirements

A condensate drain must be installed under the following conditions:

•All vertical terminating vent installations

•Horizontal terminating vent installations where the total equivalent exhaust vent length is greater than 10 feet. See table 17, page 33.

Room sealed installation (TWIN PIPE SYSTEM)

Installing this water heater as a room sealed (TWIN PIPE SYSTEM) is the recommended method. Contact your dealer for available vent termination kits and vent materials for this water heater.

The exhaust and combustion air piping must vent directly to the outside of the structure.

•Vent installations where any section of the exhaust vent pipe passes through an unconditioned space.

Note: Do not install condensate drain in areas where it may freeze.

1.Install condensate drain as close to heater as possible.

2.Use 3/8" ID high temperature silicone tube to connect to condensate drain port. Do not use copper piping for any portion of the condensate drain.

3.Form a condensate trap by means of a 3" loop partially filled with water.

4.To increase the tube length, connect to end of the high temperature silicon tubing with vinyl tubing, PVC or CPVC pipe. Do not reduce the internal diameter at any point.

5.Dispose of condensate according to local codes.

Warning: In areas where outside temperatures routinely come close to freezing, sealed combustion operation is required. Use a concentric termination or separate terminations for combustion and vent, which must be installed on the same wall or roof surface, however never facing the direction of prevailing winds. Failure to do so may result in heat exchanger freezing up and bursting. This failure is not covered under the manufacturer's warranty.

GWH 2400 ES NG, GWH 2400 ES LP specifications

Bosch Appliances has established a reputation for delivering high-quality and innovative home solutions, and the Bosch GWH 2400 ES LP and GWH 2400 ES NG are no exceptions. These high-efficiency water heaters are designed to provide on-demand hot water, ensuring comfort and convenience for your home.

One of the standout features of the Bosch GWH 2400 ES LP (Liquid Propane) and GWH 2400 ES NG (Natural Gas) models is their compact, space-saving design. These tankless water heaters are engineered to fit in smaller spaces, making them an ideal choice for homes with limited installation areas. Despite their compact size, both models provides a powerful performance that meets the hot water needs for multiple fixtures simultaneously, such as showers, faucets, and washing machines.

These water heaters are equipped with advanced technology that enables precise temperature control. The Bosch GWH 2400 ES series utilizes a microprocessor-based control system that allows for consistent water heating, ensuring the water temperature remains stable even during high demand. The modulating gas valve further optimizes energy consumption, adjusting the flame intensity to meet the exact heating needs, thus enhancing efficiency.

In terms of safety, both the GWH 2400 ES LP and NG come with multiple safety features. These include a flame failure safeguard, overheating protection, and a built-in freeze protection system. Such features ensure both peace of mind and the longevity of the unit.

Installation is straightforward with these models, as they can be vented using standard venting materials, saving time and costs. Additionally, the units boast a low NOx emissions rating, making them environmentally friendly choices that help homeowners reduce their carbon footprint.

Maintenance is minimal, thanks to the corrosion-resistant heat exchanger which ensures durability and long service life under normal operating conditions. This factor, combined with Bosch’s renowned commitment to quality, makes these models a reliable investment for any household.
